Life Cycle
Larvae feed on dried plant material, including dried flowers, straw, spices, and, especially, hay stored in traditional haystacks, where sometimes a pest. Larvae cover stored plant material with silk.
H. costalis rarely, if ever, has the AM and PM lines which are typical in D. olinalis (Hugh McGuinness pers. comm.)
