Trichogramma are tiny wasps that parasitize insect eggs
(North Carolina Cooperative Extension).
Pupae are formed within an earthen cell 2 to 5 inches
deep in the soil (Cornell University).
Larvae feed on corn kernels within the ear. Larvae vary in
color from green to brown to black (University of Minnesota).
Corn earworm moths lay their eggs on fresh corn silk. Note
the tiny white eggs stuck on the silks (Cornell University).
