Papilio cressida insularis
This is the sole member of this family. Unlike other male Papilio this species has no valvae, or claspers in the genitalia. Instead there is a hook like projection. The female has transparent wings and after copulation some of the sperm create a pouch like structure 'sphragis' on the abdomen.
they are seen around flowers and when disturbed it changes its usual lazy flight to one of great speed.
