If a wasp spider has taken shelter or is living in your home, you should be aware that the venom from these spiders may prove to be harmful. While most wasp spiders are not considered dangerous, species from the genus Steatoda and others mentioned below can cause serious damage to both humans and pets if venom is injected. All wasp spiders are venomous and use venom to paralyze their prey. Their venom contains a neuromuscular toxin, although no fatalities have been reported due to their bites. Wasp spiders can range in coloration from brown to black, and may be yellow, white or striped.
Is A Wasp Spider Poisonous
For decades, only the gardens of the South Coast were warm enough for them
But after years of mild winters, one of Britain’s most colourful and striking spiders is on the march.
The population of the wasp spider has exploded and is spreading rapidly north.
This year, females have been spotted in Surrey and Hertfordshire.
By the end of the autumn – the season when spiders are most in evidence – they could have spread well beyond the Home Counties.
Wildlife experts urged gardeners yesterday to be on the lookout for the creatures over the next few weeks -and report sightings.
Originally from the Mediterranean, they were discovered in England in 1922 where the climate was just warm enough for them to survive.
For decades they clung to the sunnier South Coast but in recent years have been seen as far north as Cambridge.
Many conservationists believe their move northwards is linked to our warmer climate since the 1970s.
Stuart Hine, of the National History Museum, said: “We are getting a lot of reports of people finding
them in their gardens. Last year we had unprecedented numbers.
“We are about to start the spider season – when females are at their largest and when the males look for mates – so we could see more.”
Female wasp spiders are around the size of a 2p piece, with body marking resembling those of wasps and bees.
But while they can bite, the creatures are not poisonous.
The males, which are far smaller and brown, are often eaten by the females after mating.
Because of this danger, males lurk on the edge of the female’s web until
she sheds her skin.
For a while after this process her jaws are soft so he can mate in relative safety.
Despite such precautions, many males are still devoured by their partners.
The females leave their egg sacs on grass leaves and therefore can only thrive in areas where grass is not regularly grazed or mown.
The species – Argiope bruennichi – eats beetles, flying insects and grasshoppers.
Experiments have shown that they are also capable of dealing with the fearsome bombardier beetle.
The bombardier beetle can produce a blast of hot chemicals from the tip of its abdomen.
By wrapping the beetle in silk, the spider can immobilise it from a safe distance.
“They are a prickly, spiny spider so if you pick one up it can feel like you have been bitten,” said Mr Hine.
“But they are harmless.”
Hertfordshire’s biological records centre has had four sightings of females in the last year.
Climate has been linked to the spread of a number alien species across Britain in recent years.
Among them are scorpions which are reported to have migrated from colonies in London’s docks.
Is A Wasp Spider Poisonous
The Wasp Spider is not poisonous, but it does have a rather unique look that can be mistaken for many other spiders. It has two body types: one that resembles a wasp and another that resembles a tick.
The Wasp spider is a relatively large spider with a body length of about 1 inch. It has long legs and its abdomen is thicker than the rest of its body. This gives it the appearance of an insect when it runs around quickly in search of prey.
It has eight eyes on its head and one pair of eyes on each leg segment. It also has large fangs, which are used to inject venom into its prey in order to paralyze and kill it. Their venom contains chemicals called sphingomyelinase D, which causes paralysis in insects and mammals alike.
Wasp spiders are brownish-black or dark gray in color and have stripes running down their abdomen from their thorax to their legs segments with black spots on them as well
