larva feeds below the surface of the water between spun leaves of
several aquatic plant (Belgian Lepidoptera).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation takes place in a large, pinkish, oval cocoon attached
to a stem or debris (Belgian Lepidoptera).
The adult is illustrated in UKMoths
(by Keith Dover) and Belgian Lepidoptera. The male
and female genitalia are illustrated by the Lepidoptera Dissection Group.
