The Rare Green Huntsman Spider is real; it lives in Britain, and volunteers just photographed one at Old Lodge Nature Reserve in Ashdown Forest. The species is Britain’s only native huntsman, and it is not dangerous to people. The find surprised even people who know this spider family from its huge Australian relatives.
The bright green spider turned up during an ordinary late October volunteering session, hidden in plain sight. Everything you need to judge an encounter is in the sections below, starting with where the find was made.
Key Takeaways
- Volunteers found a green huntsman at Old Lodge Nature Reserve in late October.
- One of those living things does not have native of people huntsman spider in this place Britain.
- It is not dangerous to humans.
- Adult females measure 12-16 millimeters long.
- The species is classed as nationally scarce in Britain.
- It hunts by day and never builds a capture web.
- Unmown green habitat near woodland edges is what it needs to survive.
Rare Sighting at Old Lodge Nature Reserve
In late October, volunteers doing conservation work at Old Lodge Nature Reserve in Ashdown Forest found a striking bright green spider hiding in plain sight. The spider was a green huntsman, and the volunteers worked for Sussex Wildlife Trust. The find came out of ordinary conservation work, not a targeted survey, which is exactly why chance sightings matter.
The charity shared a photograph taken by Ellie Stradling, and the image let other recorders confirm the species at a glance. Old Lodge covers 74 hectares of heathland, grassland and woodland, and you can check the reserve’s setting and trails on the Sussex Wildlife Trust reserve page. It sits near Uckfield, in the heart of Ashdown Forest.
The species is an established resident of Ashdown Forest, although sightings remain relatively uncommon. That makes a verified photograph valuable even inside a known stronghold. Records like this help map where the species actually lives from year to year.
The reserve itself points visitors to one reliable spot: green huntsman spiders turn up there among purple moor-grass during the warmer months. Heathland next to woodland gives the spider both the shelter and the prey it needs.
A little attention came from the name. This species belongs to the same family as the enormous huntsman spiders people associate with Australia, which is why a small British find drew so much notice. The find was a photograph of an adult female, and she was exactly where this species is supposed to be: low vegetation on a heath and woodland edge.
What Is a Huntsman Spider, Really?
The green huntsman is not a weird one-off; it is a member of Sparassidae, the huntsman spider family, one of the most successful groups of hunting spiders on Earth. Sparassid legs twist rather than joint vertically, so the legs extend forward in a crab-like way instead of hanging straight down from the body. That single trait defines the whole family.
The family is also called the Giant Crab Spiders, a nod to the size and the sideways leg arrangement. The legs let a huntsman sprawl flat against a surface and slip into gaps most spiders cannot use. Some larger species are known as Wood Spiders for their preference for woody habitats.
Sparassid eyes sit in two rows, a layout you can check with a hand lens. The family catches prey by hunting rather than building webs, so every huntsman you meet is an active predator. Speed and stealth do the work that silk does for orb weavers.
Most huntsman species live in warm, temperate or tropical regions, which makes a native British one unusual. One family curiosity pushes that further: an eyeless cave-dwelling species in Laos lives out its life in total darkness. The green huntsman keeps its small eyes and its daylight habits.
What sets the green huntsman apart inside this family is not its hunting style but its color, and that color deserves its own explanation.
How Big Is a Green Huntsman Spider?
An adult female green huntsman measures 12-16 millimeters long, and a male only 7-10, which makes this spider a thumbnail-sized hunter rather than a hand-sized one. Gravid females can occasionally reach up to 17 millimeters, but even then the body stays shorter than a fingernail. Females in Britain typically measure up to 15 millimeters.
The table below puts those numbers next to the family your mind jumps to first.
| Sex or measure | Body length | Leg span |
|---|---|---|
| Adult female green huntsman | 12-16 mm | Not recorded for this species |
| Adult male green huntsman | About 7-10 mm | Not recorded for this species |
| Huntsman spiders as a family | About 1.8 cm body | Up to 15 cm leg span |
That gap explains why the Ashdown Forest find surprised people. A giant huntsman from Australia can cover a dinner plate with its legs. The British species fits under a coin with room to spare.
The size also explains the hunting style. A thumbnail-sized spider cannot overpower big prey, so it takes small flying insects instead. Scale matters when you picture an encounter.
At that size, the surprise of finding one comes from the color, not the bulk, because you can cover this spider with a two-pence coin.
Why It Is Vivid Green
The green is not a trick of the light; it is a pigment called micromatabilin, carried right through the spider’s body fluids and tissues. Micromatabilin is a bilin pigment, and it colors the haemolymph, the interstitial tissues and even the egg yolk of Micrommata virescens. The green runs deeper than the skin.
The Pigment Behind the Green
Bilins are the same family of pigment molecules that give bile and some bird eggshells their colors. In this spider the pigment sits everywhere light passes through the body, so the whole animal reads as one even green. The color does not appear at birth: it develops in the spider’s second spring, ahead of the final molt.
Camouflage in Full Sunlight
The flat body pressed against a leaf kills its own shadow, and the green matches the leaf’s surface exactly. Even in full sunlight the spider is nearly invisible against a leaf. Birds and other predators pass over it, and small insects never register the shape waiting below them.
The same color would fail on a building wall, which is why brown and grey huntsman species that live around human buildings use those duller shades instead. Each habitat selects the camouflage its walls and leaves demand.
Sit a green huntsman on a leaf in bright sun and it all but disappears, which is exactly the point for both its hunting and its survival.
Where the Green Huntsman Lives
Find the right vegetation, and you have found the green huntsman’s home: damp meadows, forest edges, heathland and grassy woodland rides. The species lives where lush green cover stands at knee height, and almost nowhere else. Green camouflage needs green plants to work, so habitat and color are one system.
The places to picture are specific, not vague. Walk a site and look for these micro-habitats:
- Damp grass meadows with tall sward
- Woodland edges and sunny clearings
- The lower branches of young oak trees
- Large clumps of heather
- Bracken stands
- Sedge tussocks
Moorland and heathland hold the species too, and so do parks. Gardens count only when they sit close to ideal habitat; a mown suburban lawn next to a busy road will never hold one. The spider needs connected green cover, not a single planted border.
Every habitat on the list shares one thing: sheltered vegetation where the spider can press flat against a leaf and wait. The common thread is sheltered green vegetation at knee height, which is why mown lawns and bare fields hold none.
The Rare Green Huntsman Spider in Britain Today
The Rare Green Huntsman Spider is Britain’s only native huntsman, and it is officially classed as nationally scarce. Nationally scarce means the species is never abundant anywhere in Britain, even at its strongholds. That classification is the concrete answer to how rare it is.
The stronghold sits in southern England, especially woodland, heathland and areas of long grass, stretching into southeast Wales. Outside that core, lone finds keep turning up. A specimen was photographed in Liverpool in September 2023, and a female turned up in a Northamptonshire forest in October 2023, both far from the main range.
Ireland holds the species too, but thinly. There it is rare and mainly confined to the southwest, including Killarney National Park. Each country’s records cluster in its greenest, mildest corners.
The wider range shows how far the species can stretch when climate allows. Micrommata virescens is a Palearctic species, found from England across Europe to Russia, Turkey, the Caucasus, Iran, Central Asia, China, Korea and Japan. Britain sits near the cool northwestern edge of all that.
Even inside its strongholds the spider is never common, which is why every verified record is worth reporting.
A Hunter That Never Builds a Web
The green huntsman never builds a capture web; it relies on camouflage, speed and a well-timed pounce to catch its prey. These spiders can and do jump, but the jump is a hunting and escape move aimed at prey, never at people. You will not be ambushed from a wall.
The hunting posture is patient and precise. The spider waits motionless on vegetation with its head facing downwards, then pounces at great speed when prey comes close. It is a competent jumper, using that skill both for catching prey and for escaping predators.
Silk still matters to this spider, just not as a trap. Draglines steady its fast running, silk lines its retreat, and silk wraps the egg sac. The capture web is the only silk product missing.
Typical prey reads like a list of small garden insects:
- Small flies
- Gnats and midges
- Mosquitoes
- Small beetles
- Other small invertebrates
- Honey bees, taken by larger females
Speed is the family trait that scales with size: huntsman spiders move extremely quickly, sometimes adding a springing jump while running, and larger species can walk up walls and across ceilings. It hunts mainly by day, although finds in moth traps show some individuals keep hunting through warm nights too.
How to Identify One in the Field
The eye pattern is the fastest confirmation: eight small black eyes arranged in an oval, each one ringed with short white hairs. The genus name Micrommata comes from the Greek for small eyes, and the name describes exactly what you see. Small eyes in white rings are the signature.
Run through these checks before you call a find:
- Vivid green body resting on low vegetation
- Flat, elongated profile pressed close to the leaf
- Eight small black eyes ringed with white hairs
- Long, finely haired legs suited to smooth leaf surfaces
- No web anywhere near the spider
The flat body is the second clue, because the spider hugs the leaf surface instead of standing tall on its legs. The legs spread crab-like and carry fine hairs that grip smooth leaves. Together those marks rule out almost every other British spider.
One honest confusion risk remains: the green crab spider, Diaea dorsata, which is much smaller and rounder. In Britain nothing else green on low vegetation comes close. If your spider is green, flat, leggy and webless on low vegetation, you almost certainly have Micrommata virescens.
Males Versus Females
You can sex an adult green huntsman from across the path: females are the bright green ones, males are the darker olive ones with red markings. The strong color difference between the sexes is sexual dichromatism, and it is unusually clear in this species. Size separates them too.
The table shows the differences at a glance.
| Feature | Female | Male |
|---|---|---|
| Body color | Bright green | Dark green-olive |
| Abdomen | Lighter green with a darker green median stripe | Red to red-brown median stripe bordered yellow, with red sides |
| Body length | 12-16 mm | About 7-10 mm |
A female’s abdomen carries a darker green median stripe down its lighter green surface, and the whole animal looks like a fresh leaf. The male looks like a different creature altogether, marked in red and yellow on a duller olive ground.
The red on a male’s flanks is why old records once treated the two sexes as separate species, a story that returns in the history section. Early naturalists simply never guessed one animal could wear both outfits.
From Mating to Spiderlings
A green huntsman’s year of motherhood starts in June, and it is a job the female does at real cost to herself. Males die within a few days after mating, and a male that fails to retreat quickly can be eaten by the female. The whole cycle runs on a tight seasonal clock.
Mating and Its Risks
Mating most commonly takes place around June, when both sexes are adult and the females are fertile through to September. Courtship carries a real danger for the male, because slow retreat after mating can end in him becoming a meal. One captive pair mated for four and a half hours in front of the media at a German museum in 2004, a duration few observers expected.
The Brood Retreat and Egg Sac
In July the female builds her brood retreat, a shelter of leaves stitched together with silk, placed 30-50 centimeters above the ground, often on oak saplings or bracken. She encloses her egg sac inside it and then guards the structure without leaving it unattended, even to feed. She defends the egg sac and her young against any perceived threat.
Spiderlings and Dispersal
The eggs hatch after about 4 weeks, producing about 40-50 spiderlings. The young disperse to live independently in late July or early August, within about a week of hatching. From there each spiderling faces roughly 18 months of growth before it reaches maturity.
Few spiders guard their young this closely, which makes the species a standout even within its own family.
The Color Changes With the Seasons
New green huntsman spiderlings hatch bright green and look like tiny garden peas with legs. The green color builds up in the spider’s second spring, before the final molt, not after it as many sources incorrectly claim. That timing detail separates careful records from copied ones.
The summer shifts the colors along with the vegetation. As the plants dry out, juveniles turn light tan, pale yellowish-green, greenish-brown or mixed green and brown. Some carry reddish-brown stripes, flecks and spots through this phase.
By winter all the juveniles tend to be brown, matching the dead stems they shelter in. The cycle has a scientific name: seasonal polyphenism, one animal producing different color forms as the season demands. Camouflage follows the landscape, not a fixed template.
Not every individual follows the script. A small number keep reddish-brown coloring right up to maturity, so an adult with brownish tones is not impossible. By their second spring the rest wear the adult green again, timed to the new leaves they will hunt among.
Are Huntsman Spiders Dangerous to Humans?
Huntsman spiders are not dangerous to humans; in a prospective study of 168 definite bites, not one case required anything beyond mild local effects. Pain or discomfort occurred in every case, but it was severe in only 27% and lasted a median of 5 minutes. That is the whole medical footprint.
The table collects the study’s findings.
| Outcome of the 168 definite huntsman bites | Result |
|---|---|
| Pain or discomfort | 100% of cases |
| Severe pain | 27% |
| Median pain duration | 5 minutes |
| Bites after the spider was interfered with | 76% |
| Systemic effects | 4%, minor nausea and/or headache |
| Necrotic ulcers or allergic reactions | None recorded |
The 76% figure deserves a second look. Nearly every bite happened after someone picked the spider up or disturbed it while handling an object. The spider bit in self-defense, not out of aggression.
Context helps too. The Australian Museum defines dangerous as deadly, and by that standard its list holds funnel-web spiders, redback spiders and their relatives, Phoneutria spiders and recluse spiders. No huntsman appears on that list, and huntsman bites usually do not need hospital treatment.
The clearest safety rule comes from the same data: leave the spider alone and the chances of being bitten at all drop to almost nothing.
Huntsman Spiders Around the World
The family the green huntsman belongs to counts 99 genera and 1,550 species as of January 2026, and most of them live in the tropics. Most sparassid species live between roughly 40 degrees south and 40 degrees north latitude, which makes the green huntsman’s cool-climate Palearctic range a genuine exception. The British species sits far outside the family’s comfort zone.
Huntsman prey usually means insects and other invertebrates, but large tropical species occasionally take small skinks and geckos. That tells you how much the family scales with size.
The Largest Huntsman Species
The world’s biggest huntsman is the giant huntsman, Heteropoda maxima, whose males reach a leg span of around 25-30 centimeters. It was found in Laos, and its legs would span a dinner plate. Next to that, the green huntsman’s thumbnail body is a family dwarf.
Other Famous Huntsmans
Three species show the family’s range best.
| Species | Where it lives | Notable fact |
|---|---|---|
| Giant huntsman, Heteropoda maxima | Laos | Leg span around 25-30 cm |
| David Bowie spider, Heteropoda davidbowie | Malaysia | Described in 2008, named after the musician |
| Green huntsman, Micrommata virescens | Europe to Central Asia | Britain’s only native huntsman |
The David Bowie spider is a large hairy orange huntsman from Malaysia, and its name made headlines when scientists described it in 2008. Against giants like the giant huntsman, Britain’s green species looks like a family dwarf, which is part of why people struggle to believe it is a huntsman at all.
How to Spot One Yourself
Your best window is May through July, in damp green vegetation, with adults harder to find than the habitat suggests. Adults appear from around April or May through July, and some specimens persist until October. Females show best from May to August, males from May to June.
Five field tips will put you in the right place at the right time:
- Search warm months in damp meadows and woodland edges
- Scan tall grass and young oak lower branches at knee height
- Check purple moor-grass clumps on heathland
- Look for the stitched-leaf brood retreat in July
- Expect juveniles rather than adults outside late spring
Late summer offers a strange bonus: three generations at once. Adults, juveniles from the previous year and newly hatched juveniles can all be present in the same patch of vegetation. Few British spiders stack their generations that visibly.
Even experts record this species as difficult to find, so an empty afternoon proves nothing. Moth trap finds show some individuals stay active at night, which slightly widens your odds. Photograph, do not collect: a clear photo of the eye pattern and the body from above is enough for a record to count.
Where the Name Comes From
The scientific name Micrommata virescens has stood since 1757, when the naturalist Carl Clerck first described the species. At first the male and female were believed to be two different species: Araneus virescens for the female and Araneus roseus for the male. The red-flanked male fooled the early naturalists completely.
Germany made the species a public cause in 2004, when it was declared spider of the year. The title brought the green huntsman into newspapers and museum displays across the country. Awareness campaigns like that one lift a species out of obscurity.
Across its range, local names describe how people actually see the spider:
- Green Whoosh Spider (Grüne huschspinne), Germany, a reference to its sudden bursts of speed
- Emerald Spider, Denmark and France
- Green Meadow Hunter, Italy
- Green Leaf Spider, Sweden
- Green Hunting Spider, Finland
The German Green Whoosh Spider is the most honest name of all, because speed is the trait everyone who watches this spider mentions first.
Why This Species Needs Its Habitat
Globally the green huntsman is not threatened, but in Britain its nationally scarce status rests entirely on the survival of structurally rich green habitat. The species depends on suitable vegetation, and the loss of structurally rich habitats can cause local declines. Rare habitat, not rare genetics, keeps the species rare here.
The habitats it needs are easy to name and easy to lose: sunny meadows, forest edges, hedgerows and semi-natural grasslands with lush ground cover. Broader research on climate pressures adds weight, since a scientific review links heat exposure to changes in spider survival, development and behavior across the group. Read that context in the review on climate change and spiders.
What the species needs from land management comes down to three habits:
- Unmown damp grass margins
- Woodland edges and clearings left open to sun
- Structurally rich vegetation with tall grass and shrubs
An ordinary person controls more of this than it seems. Leaving rough vegetation edges in gardens and parkland next to good habitat can help the species hold on. Every unmown field margin near a meadow or woodland edge is potential habitat for a spider that cannot live anywhere else.
Conclusion
The rare green huntsman spider turns out to be neither rare-looking nor frightening, only easy to overlook. It is small and harmless, and its true rarity in Britain comes from its need for lush green habitat that modern land use keeps erasing.
If you think you have found one, photograph it from above and send the record to a national spider recording scheme or your local wildlife trust. A clear photo of the eye pattern is all a verifier needs. That is how this species’ map gets drawn, one careful sighting at a time.
FAQ
How aggressive is a huntsman spider?
Huntsman spiders are not aggressive toward people. In the study of 168 definite bites, 76% happened after someone picked the spider up or disturbed it while handling an object, so interference rather than aggression causes nearly all bites. A huntsman that is left alone has little reason to bite, and it will usually run away instead of standing its ground.
What is the #1 deadliest spider?
The Australian Museum defines dangerous as deadly, and its list of the world’s most dangerous spiders includes funnel-web spiders, redback spiders and their relatives, Phoneutria spiders and recluse spiders. No huntsman spider appears anywhere on that list. Funnel-webs and redbacks, both Australian, are the names most often cited when people rank the deadliest species.
Is the green huntsman spider rare?
Yes, it is classed as nationally scarce in Britain and is never abundant even where it is present. Its stronghold lies in southern England and southeast Wales, in woodland, heathland and areas of long grass. Scattered records from places like Liverpool and Northamptonshire in 2023 show lone finds well outside the core range.
Does the green huntsman spider bite humans?
Bites are possible but usually mild and rarely need hospital treatment. In the bite study, pain was universal among 168 definite huntsman bites, but it was severe in only 27% and lasted a median of 5 minutes. Systemic effects appeared in just 4% of cases, as minor nausea or headache, and no necrotic ulcers or allergic reactions were recorded.
How long do green huntsman spiders live?
Green huntsman spiders usually live 1-2 years in the wild. Growth is slow for a spider of this size, because about 18 months pass before a spiderling reaches maturity. That long development means an adult you find in spring has already survived a winter in its brown juvenile colors.
When is the best time to see a green huntsman spider?
Adults can normally be found from around April or May through until July, with some specimens persisting until October. The best months are May to August for females and May to June for males. Late summer offers a bonus: adults, older juveniles and newly hatched juveniles can all be present at once.
