Life Cycle: Overwinter as adults outside orchards. Eggs (orange, elongated) are laid in clusters on underside of leaves and branches. Usually only one generation per year.
Monitoring: Inspect colonies of aphids for adults and/or larvae.
Hosts: Aphids, mites and scales, soft-bodied insects.
Comments: There are many species of ladybird beetles that vary in size, colour and pattern. Depending on species, colours are black, red, orange-red to almost yellow. Most species have coloured spots or markings on their backs. One small (1.0mm long) species of ladybird beetle, Stethorus picipes Casey, commonly known as the red spider destroyer, feeds on mites and scales.
Body length: Adult - 1.0-5.0mm; Mature larva- 1.0-7.5mm
