One of the special jointed organs situated on the under side, and near the end, of the abdomen of spiders, by means of which they spin their webs. Most spiders have three pairs of spinnerets, but some have only two pairs. The ordinary silk line of the spider is composed of numerous smaller lines jointed after issuing from the spinnerets.
a spiders silk spinning organ
a tube-like structure on a larva s lower lip labium
a specialized nozzle-like organ connected to an internal silk gland that allows an insect larva to spin a silk thread. Butterfly caterpillars spin silk threads that they can follow so as not to get lost, and to suspend their chrysalis from a leaf or twig. Many moth larvae spin protective silken cocoons during metamorphosis from larva to pupa.
Gland beneath the caterpillar's head used for producing silk
(noun) opening of the silk gland
a small tubular appendage from which silk threads by spiders and many larval insects
Organ on the bottom of the larva head used to spin silk; in spiders.
A spinneret is a tube-like structure on a larva's head that contains the spinning apparatus of the larva (caterpillar). The caterpillar draws silk (which is made in the salivary glands) from a tube in the spinneret. The silk dries when exposed to the air. Caterpillars use this silk to support themselves and to make webs and cocoons.
A spinneret is a spider's silk-spinning organ. It is usually on the underside of a spider's abdomen, to the rear. Most spiders have six spinnerets; some have four or two.
