Similar Species:
Poecilus lucublandus is metallic green and identical, except it has a wide rim or shelf on thorax sides.
Anisodactylus laetus is also metallic green, thorax not constricted at lower margin and legs are reddish-brown.
Harpalus affinis is also metallic green, thorax not constricted at lower margin, and has entirely orange-red legs.

Size: 10 to 13 mm.

Habitat: Crop fields like soybean, alfalfa and corn; wetland edges. Prefers moist soils.

Food: Cutworm moth larvae, beetle eggs and other small insects.

Flight Time: May to September.

Life Cycle: Mating in May. Over-winters as an adult, found under stones and dead leaves. Active at night, attracted to lights. Larvae are cannibalistic, need moist soil for survival.
