The female reproductive opening is located on the underside of the abdomen, near the front of the spider. It is called an epigynum and is often hardened and dark in colour. Female Badge Huntsman Spider underside. Note the reproductive opening, the epigynum.
Adult females have a larger body size, especially the abdomen, than males. Adult males have longer legs than females, and the long male palpi have the terminal segment enlarged and the ventral sclerites exposed, as in most true spiders.
Males, when they become adult, are distinguished by the sex organs on the ends of the palps which look rather like a pair of boxing gloves. The males usually die in the autumn soon after mating, but many females survive to the next year, during which they produce a number of egg-sacs.
The average huntsman spider(opens in a new tab) has a body span of 2 centimetres (0.7 inches) for females, and 1.6 centimetres (0.62 inches) for males.
If you try to catch a huntsman and it runs towards you, it isn't attacking. It is trying to get to a safe place, away from the giant human thing looming over it. Given they have poor eyesight, sometimes they get it a little wrong and head towards us instead of away from us.
There's not enough food inside a house for a huntsman spider, so they're best off outside." Dr Harvey said the safest method, for both people and spiders, was to use a container. He said while they can give a painful bite, they don't pose a risk to humans.
Spiders dislike the scent of peppermint, eucalyptus oil, tea-tree, or citrus. Thus, regularly spraying them down likely entrances deters them from coming in. Simply fill a standard spray bottle with water. Then mix it with 15 to 20 drops of the essential oil.
Huntsman spiders are not normally aggressive towards humans (except for females guarding their egg sacs). They are more likely to run away than attack, unless provoked.
The female Huntsman (Isopeda, for example) produces a flat, oval egg sac of white papery silk, and lays up to 200 eggs. She then places it under bark or a rock, and stands guard over it, without eating, for about three weeks.
The majority of huntsmen are solitary; they live on their own and only come together briefly to breed. The exception is the Social Huntsman (Delena cancerides) which live in large groups beneath bark.
The resultant data shocked researchers, as a whopping 82 percent of house spiders encountered were male. Although this is a high percentage, this data makes sense in that male spiders must search their territory for female mates. Females were encountered far less often because they tend to stick to one place.
Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
Don't hunt the huntsman!
They can bite and it does hurt but is rarely harmful. As house guests, they earn their board by controlling cockroaches, flies and other unwanted nasties, providing chemical-free pest control. Weather is expected to drive more indoors and wildlife experts urge to leave the arachnids alone.
Can we really trust them to leave us alone when they're lurking high up on our bedroom wall? "Huntsmen don't have very good eyesight. They see light and dark and movement and that's about all. They will never intentionally run towards you because they're small and not highly venomous.
Your house or car are dry, and while not the most attractive guest, your harmless huntsman won't want to stay forever either. If you can bear to leave it there when you go out, you might well find it gone when you come home. Huntsman do not weave webs like other spiders to catch their food.
Food: Live insects. Crickets, cockroaches, moths and flies are ideal. The food insects should be no larger than 1/3 of the size of your spider. Feeding twice a week is recommended, but young spiders will feed more often when they are growing.
Their early diet consists of tiny insects such as fruit flies, small house flies, and baby crickets. It will be eight to 12 months before the babies will be fully grown.
Feed your spider live insects 2-3 times a week.
They also like cockroaches. You can even just catch insects around your house or yard, as long as you haven't treated the area with insecticides or pesticides.
During the day, most huntsman spiders prefer to retreat in protected areas, like under rocks and the bark of trees. Although, most people encounter these spiders at home and in their car, whether it be inside a curtain ripple or the back of their car sun visor.
Is It Safe To Handle A Huntsman Spider? It is not advised to handle any wild or unknown spider. You should not pick them up or trample on them with your bare feet. If you threaten them by picking them up or treading on them, they will bite you.

If you're the sensitive type who finds scented insect sprays a little heavy on the nose, Mortein Kill & Protect Odourless Crawling Insect Killer will do the trick.
Second, they are very smart. While the different species of huntsman spiders run at different speeds, the fastest among them run at rates comparable to Olympic sprinters, while the slower among them still run at speeds similar to a reasonably fit human's running speed.
Simon Lockrey, industrial design research fellow and former vacuum cleaner design engineer: It certainly could, depending on the vacuum cleaner. If there is a clear way out, the huntsman could make its escape when the vacuum is turned off.
