|| FOR YOUR INFORMATION: The insect order Embiidina (=Embioptera), or
more commonly known as webspinners, is a small group of insects (i.e., about
2,000 species worldwide). They are found mainly in the tropics with about
9 species found in southern United States. Both sexes, immatures, as well
as adults, spin silken tunnels from secretions of silk glands located in
the tarsi of the front legs or forelegs. Ed Ross of the California Academy
of Science is a specialist on this insect group and has given permission
to use his excellent photograph of an adult webspinner.|
||The fore tarsus of the webspinners is modified to produce and secrete silk.
The liquid silk comes out of the silk ejectors, which are located on the
ventral surface of tarsal segment III. The silk gland contains sbout 200
syncytial cells and is functional throughout the life of the insect.|

webspinners live (courtesy of Dr. Ross).|
