Coccinellidae, subfamily Coccinellinae
The Coccinellidae Latreille, 1807, are generally considered useful insects, because many species feed on aphids or scale insects, which are pests in gardens, agricultural fields, orchards, and similar places. Within the colonies of such plant-eating pests, ladybugs will lay hundreds of eggs, and when these eggs hatch, the larvae will commence feeding immediately. In Harmonia axyridis, eggs hatch in 3–4 days from clutches numbering from a few to several dozen. Depending on resource availability, the larvae pass through four instars over 10–14 days, after which pupation occurs. This spotting is that of a pupa of an unidentified lady beetle.
