Webspinners

RELATIVELY SMALL GROUP, the

-order Kmbioptera contains just 8

families and 300 species. Web-spinners are gregarious insects whose common name is derived from their ability to make expansive silk tunnels in soil, in litter, and under bark. These are used for protection against predators.

Web-spinners' legs are short. Adults and young of all species have a swollen tarsal segment on their front legs, which contains silk glands. The silk is ejected through the many bristlelike structures found on the underside of the segments. As the insect moves its front feet against a surface, a silk sheet gradually forms.

Females are wingless, while the males typically have two pairs of narrow wings.

The females and nymphs remain within the colony, but adult males fly off to find mates in other colonies. Metamorphosis in this order is incomplete.
