Seedcorn Maggot

The seedcorn maggot is yellowish white, legless and about ¼ inch (6 mm) long that can be active in early spring as it feeds on the germinating bean and seed. Wireworms are slender, yellowish, hard-bodied larvae that may grow to 1 inch (25 mm) or more in length; they feed on roots and hypocotyls. Both pests can cause plant stunting and death.
