Trichogramma Wasps in Giant Swallowtail Papilio cresphontes Butterfly Eggs
Trichogramma wasp larvae eat the contents of butterfly and moth eggs. After chewing a hole in the egg shell, the adults emerge to pair and lay eggs in other lepidoptera eggs. Adult trichogramma wasps eat nectar, sweet fluid which some plants emit and/or droppings of other insects such as aphids, and ripe fruit.

Trichogramma wasps can be purchased to control 'worms' (caterpillars) in crops or gardnes. Many of these 'worms' are butterfly and moth larvae. Their lifecycle takes appx 17 days.
