The larvae are typical maggots, less than 1/4 inch long, legless and cylindrical, tapering to a point at the head, dirty-white to creamy-yellow in color. Seedcorn maggots feed underground on cotyledons and can also burrow into seeds. Damage from this insect is accentuated when cool, wet weather delays sprouting and emergence. The adult flies, similar to house flies, are attracted to decaying organic matter.
