A 1893 note from Science by H. Garman on silk-spinning fly larvae (Diptera), including cave-dwelling Mycetophilid larvae from Kentucky caves and Simulium larvae in streams. He argues that their threads count as silk in a biological sense, produced by special glands and used like the silkworm's product, even if not chemically identical to commercial silk. The article describes web-building behavior, the slime coating on the larvae, the pupa, and a letter from H. G. Hubbard on a similar Jamaican cave larva. Four line figures show larvae, a web and a pupa.

A short 1893 entomological note by H. Garman describing a silk-spinning larva found on limestone cave walls near Lexington, Kentucky, probably the young of a cave-dwelling fly. It covers the larva's body structure, the pads it uses to cling to and move along its silken thread, and its likely habits and food. The author compares it with a Mammoth Cave larva he described in 1891 and with other silk-producing Diptera. It has no connection to weaving or textile practice beyond the natural silk thread.
