Hippodamia convergens (predator) Guerin-Ménéville, 1842 - (convergent ladybeetle)

The ladybeetle is a predator of aphids and Lepidoptera eggs in North America. The 'converging' ladybird beetles can be field-collected in large numbers in North America when they aggregate. They are then used as biocontrol agents against aphids. H. convergens is particularly important as a natural enemy of cereal aphids like Schizaphis graminum and Sitobion avenae. However, it also feeds on many other aphid species. When aphids are rare the beetle goes into a reproductive diapause. It can also feeds and survive on pollen and nectar.
