spider wasp - a fairly common and extremely interesting representative of the class arachnid (spider).This class is very extensive habitat.Arachnids common in Europe and North Africa, are also found in South Asia.Representatives of this kind can be found in the eastern countries, in particular Japan and China.As for Russia, this kind of spiders live only in the southern part of the country.
Interestingly, the spider wasp prefers to live in the territory of meadows and forest edges.Sometimes, the wildlife can be found at the roadside.
Spider-Wasp: a brief description of
It is the creation of science known as Angiopa Bryunniha.I wonder what kind of got its name after the famous mineralogist and zoologist from Denmark - Morten Thrane Bryunniha.Some scientists have proposed the name "zebra spider", as the body of the spider is released very characteristic striped coloring.However, the prefix "wasp" caught on quickly.
The representatives of this type is not too large and very characteristic color - their abdomen has an interesting pattern of yellow, white and black alternating strips.This color is a bit like wasps - that made the name "spider wasp" so popular.
on the back of individuals have a tight silver shield.Cephalothorax this spider covered with hairs with the same silver coloring.By the way, at the extremity of the insect also have expressive light and dark rings.And the edges of the abdomen, there are six distinct grooves, painted in different colors, from dark shades and finishing with bright yellow and even orange.
interesting that this species of spiders is very clearly visible sexual dimorphism.Females of this kind are quite large - their dimensions are approximately 25 mm and with straightened limbs and all four centimeters.Abdomen with bright colors.
At the same time, males are much smaller - the length of the abdomen is only seven millimeters.Painting discreet.
spider wasp: the way food
feed on members of this group as well as all the spider creatures.Wasp Spider weaves a thin, trapping network (web) with a characteristic zigzag pattern.As a rule, weaving a web of insects at dusk.Interestingly, for the creation of a full trapping nets stretched between plants, the spider needs only an hour.
As mentioned, the web is very characteristic and is composed of thin filaments.In the center is the so-called stabilimentum - thick thread that forms a zig-zag pattern.It is here that the wasp spider waiting for its prey.Representatives of this group of spiders prey mainly on wasps and grasshoppers, at least - other insects.Once production gets into the trapping network, the spider immobilizes it, and enters into the body of liquid, rich herbal enzymes.Enzymes are actively digest the insect's internal organs - and they feed on the spider.
spider wasp: reproduction
spiders Mating takes place immediately after the first molt.After fertilization, the female eats the male.About a month later, females lay eggs on 300do 400 - for this form or one or several of cocoons.
Juveniles emerge from eggs in the autumn months, but until May reside in a cocoon.The female dies only once to build several (sometimes one) egg cocoons.
spider wasp poison?
This question is of interest to many.After all, the large size of the female and the bright colors of the insect's body suggest, that the wasp spider is poisonous.However, this is not true.Representatives of this group of arachnids are harmless to human health.Sometimes bite the skin may be red, inflamed.In some cases, the wound site may occur swelling, accompanied by a gentle pain.But do not worry - the bite of this spider is not dangerous to human health.
