The silk-glands whose ducts open on this spinneret are paired convoluted tubes lying alongside the elongate cylindrical stomach.
The labium or second maxillæ, so large in the moth, serves simply as a spinneret in the caterpillar.
The thread, as a matter of fact, does not flow from the spinneret; it is drawn thence with a certain effort.
One draws out the thread from the spinneret, and passes it to the other, which lays it on the radius.
The silk is stiffened with a sort of gum as it comes out of the spinneret.
When the Spider has laid her eggs, she begins to work her spinneret once more, but in a different manner.
On the skin are a number of large oval spots which appear to be the orifices of spinneret tubes.
These last open at a small orifice in the labium termed the spinneret (fig. 2, 5).
It is at once seized in the fangs, embraced by the legs and hung on to the spinneret.
It is truncated, wide open and supplied with a membranous partition, the work of the spinneret.
