parasite

The larva lives in a seed case: a dried flower of which the seed has been eaten out, and lined with silk. The mouth is where the peduncle was, and has an angle of 20°-30°. The cases are perfectly camouflaged, but the larva betrays its presence by the striking holes in the sides of the emptied fruits.
