![]() Female spider wasps usually only sting people who are attempting to handle them or are otherwise distressing them bodily. Unlike social wasps, where many females work together to build communal nests and defend the nest vigorously, spider wasps are laser-focused on their mission to find, capture, and hide their spider prey. We usually think of spiders as fierce (though smallish) predators, but this is a reminder that in nature, the predator is also often the prey.Īlthough spider wasps are rated as having one of the most painful insect stings, they are not aggressive to people. Wowie, zowie! These large, long-legged wasps attract attention as they drag their captured prey - often a good-sized spider - to its doom. The larva pupates inside a silken cocoon, and in most species, this is the form that overwinters. Interestingly, the larva generally avoids eating the spider’s vital organs until it’s almost fully grown, which keeps the spider alive and fresh. Upon hatching, the grublike larva chews on the spider’s body, which provides the nourishment for it to grow to full size. With the spider tucked away, she lays an egg on it, closes the nest entrance, and repeats the process for each egg she lays. Some species snip off some or all of the spider’s legs to make it easier to drag around. Some females dig burrows into the ground, others build mud cells or use abandoned cells of mud daubers, others use preexisting holes (such as beetle-bored holes in tree trunks, or old burrows of moles or mice), and some use the spider’s own nest or cranny. She then drags the paralyzed spider to a nest chamber.ĭifferent species use different types of nest chambers. After mating, the female spider wasp locates a suitable prey spider (each species typically has a certain group of spiders it usually hunts) and subdues it by stinging it. Males typically hold territories and perch, waiting for receptive females to fly near and fending off rival males. Pompilids are solitary wasps and do not nest in colonies. ![]() The spider-hunting behavior, often on the ground, is another strong clue. ![]() The extra long, spiny hind legs that often dangle downward in flight, and the nervous flicking of the wings are helpful characters for identification at a glance. Similar species: There are many other kinds of dark-colored, medium to large wasps in our state. Also, when you stretch the hind leg backward, parallel to the rest of the body, the outer tip of the hind femur (the leg segment analogous to the thigh) usually extends beyond the tip of the abdomen. ![]() For example, on the hind pair of legs, a spider wasp has two prominent spines at the outer end of the shinlike section (tibia) of the leg these spines point outward toward the foot segments (tarsi). To verify their identifications, specialists note details of wing venation, distinctive shapes and groove marks in the body plates, and features of the legs. Some species have orange or yellow legs or antennae. The wings are often smoky-clear, amber, or dark like the body. Some species are black with yellow bands, or have orange or rust markings. Body color varies with species: most are dark - black, shiny blue-black, or brownish. was used in the generation of this content.Spider wasps are large wasps with long, spiny legs.
