Butterfly antennae end in club shapes but moth feelers are not like this. Many types of moth have antennae that are feather-like having tiny projections along both sides in the males. They use these to track down females utilising a very elaborate sense of smell.
Butterflies fly by day but most moths are nocturnal. There are many day-flying moths as well though and these are often brightly coloured so they get mistaken for butterflies. Some moths fly by night and day. Butterflies only fly at night when migrating and covering long distances.
Butterflies rest with their wings folded back above them but moths rest with their wings flattened.
Butterflies mainly have elaborate courtship displays in which the males seek to attract the females, but with moths the females wait passively for males of their species to find them and mate with them.
