Webspinners continually extend their galleries to reach new food sources, and expand their existing galleries as they grow in size. The insects spin silk by moving their forelegs back and forth over the substrate, and rotating their bodies to create a cylindrical, silk-lined tunnel. Older galleries have multiple laminate layers of silk.
Haploembia tarsalis or the pink webspinner is a species of webspinner in the family Oligotomidae. It is originally from the Mediterranean, but was introduced to California before the 20th Century.

Oligotoma nigra, also known as the black webspinner, is a species of insect in the order Embiidina, also known as Embioptera. [1] Description.

A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. [1] Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. [2] [3] While most spiders have six spinnerets, some have two, four, or eight. [4]
After the eggs hatch, the mother stays with the nymphs and provides silk to protect them. Predators of this webspinner include ants, spiders, geckos and birds. They are particularly vulnerable when they leave the webbing and forage elsewhere, and they are also vulnerable when there are holes or tears in the webbing through which ants and ...
