Eggs laid in soil, both adults and larvae are nocturnal predators
Eggs laid in new growth of shrubs, nymphs and adults predatory
Both adults and nymphs are predatory

Enhancing habitat that adjoins fields with native flowering plants will attract beneficial insects that provide two critical ecosystem services: pest insect population control and pollination. The following chart and photos provide information on common beneficial insects and their predator/prey relationships.
Eggs laid singly on buds, leaves, or sheltered location
Both adults and larvae are predators on soft-bodied insects
Subfamily Syrphinae only; adults consume flower nectar and pollen
Larvae search for prey in leaf litter, on plants, and in the soil
Parasitic, females lay eggs on or in host
Mites, thrips
