Bucculatrix locuples

Description

Bucculatrix locuples is a moth in the Bucculatricidae family. It is found in North America, where it has been recorded from Kentucky, Quebec and Ohio. The wingspan is 6–7 mm. The forewings are black, with a faint bronzy tinge and lustrous pale golden marks. The hindwings are irrorated dark fuscous. Adults have been recorded on wing from April to May. There are two generations per year. The larvae feed on Alnus semdata. They mine the leaves of their host plant. The mine has the form of a slender thread, its early part filled with black frass. Older larvae live freely, eating irregular patches of leaf tissue, leaving the upper epidermis intact. Pupation takes place in a bright brown to almost black, hairy cocoon, which is spun on a twig.
