silk gland [′silk ‚gland]

(invertebrate zoology)

A gland in certain insects which secretes a viscous fluid in the form of filaments known as silk; it is a salivary gland in insects and an abdominal gland in spiders.

Silk Gland

in certain arthropods, an organ that elaborates a secretion that on exposure to air hardens into silk threads. Silk glands are especially developed in spiders. They are located in the posterior part of the abdomen and open through numerous tiny tubules at the ends of the six colliculi. Spiders have several types of silk glands: they secrete silk for producing egg cocoons, for arranging various parts of a snare, and for forming a sticky secretion with which the spider traps its prey. Silk glands are also found in Tetranychoidea, Pseudoscorpionidea, and Embioptera.
