Wings are clad in tiny overlapping scales. Scales can have several shapes. The base of the wing is the toughest part
Lepidopteran antennae are highly variable in shape; often clubbed, filiform or pectinate (with tiny extensions along the sides, there are 3 groups: Bipectinate, Pectinate and Quadripectinate). The sclerite at the base of the antennae can be used to couunt the number of individual lepidopteran in a pellet.
eye, proboscis, ocelli
The proboscis, is a hollow slightly curved tube. The tip is feathered with long hairs. The large multi facetted eyes have a black eye disk. Some species also have one or several simple eyes, or ocelli.

Some moth species have a frenulum, a wing coupling device.
Moth eggs are soft and flexible, shape size and structure varies between species.The male has a median tubular organ (called the aedeagus) which is extended through an eversible sheath (or 'vesica'). Fragments of the spike-like structure on the vesica (the cornuti) can be found in bat pellets.
