The larvae have been reared on snails of the genus Tornatellides and pupae of Drosophila melanogaster.

It is decorated with bits of sand, pebbles and plant fibers, finely woven between silk filaments. It is covered with orange beige scales probably deposited by the adults during emergence. Etymology
