Most species fly during the day, with some being active into dusk.
Being the poor cousins of yucca moths, this group has received little attention from biologists, and with the exception of two economically important species we know little except the species of host plant. Both species have been accidentally introduced in North America. Please note that entries for Palaearctic Lampronia are based on often scarce literature as I have little first-hand experience with them. Treatments may be incomplete or obsolete, and corrections and additions from local entomologists would be gratefully accepted. It is a heterogeneous assemblage, with several groups clearly defined on synapomorphic grounds, and there may be grounds for subdivision to bring generic diversity in line with thge remainder of the family.
