The insect is evidently a many-brooded species, since indica-tions point to at least three or four sets of the moths during thespring, summer, and fall. The larva is a web-maker, and alwaysspins as it goes and constructs a sort of retreat in which it re-mains during the day time at rest. It is described by ProfessorPopenoe in the second quarterly report for 1880 of the KansasState Board of Agriculture. He says: The following pointsin its history are the partial result of my study of the I made a careful search for the egg, I failed to discoverit in situ, but it is without doubt deposited on the lower side ofthe leaf, or low down among the bases of a cluster of leaves, asnewly hatched larvae are found in both these situations, fromwhich they soon wander to other parts of the plant. As soon asit (the larva) begins to move about it begins to spin the web,and this is increased in extent as the movements of the larva are.
