Wings: Forewings and hindwings form the two pair of wings present on the dorsal side. Forewings are the first pair of dark, opaque, thick, leathery wings. Hindwings are thin, broad, membranous delicate and transparent. They are attached to tergum of metathorax. 

Functions: Forewings are protective in function and hindwings are helpful in flight, thus are called true wings.

Why are the wings of butterfly and birds said to be analogous organs?

Wings of butterfly and birds are not anatomically similar structures though they perform similar functions. Hence, they are called analogous structures. Analogous organs result from convergent evolution.
