The common asparagus beetle (Crioceris asparagi) is an important pest of asparagus crops both in Europe and in North America. Asparagus is its only food plant. The beetle is about half a centimeter long, metallic blue-black in color with cream or yellow spots on its red-bordered elytra. The larvae are fat gray grubs with dark heads. Various insecticides are licensed for control, and the parasitic wasp Tetrastichus asparagi Crawford has been successfully used for biological control. \n* Eggs of the asparagus beetle, laid on the stem of a flower of an asparagus plant \n* Larva of Crioceris asparagi
