Adult green and brown lacewings |
Green lacewing nymph |
Life Cycle: Chrysoperla carnea and Hemerobius pacificus overwinter as adults; Chrysopa oculata as pupae. Up to four generations per year depending on temperature.
Monitoring: Examine aphid- or psylla-infested leaves and shoots for feeding larvae or use limb taps.
Hosts: Aphids, pear psylla, mites, soft-bodied insects.
Comments: Common species of lacewings include two green lacewing species, Chrysoperla carnea Stephen and Chrysopa oculata Say, and one brown lacewing species, Hemerobius pacifus Banks. Lacewing eggs are white and laid singly or in groups on long stalks on the underside of leaves or branches. The brown and green lacewing larvae are very similar except for small differences in body shape and the brown lacewing's habit of moving its head from side to side while walking.
Body length: Adult - 10.0-20.0mm; Mature larva - 6.0-10.0mm
