; subclass Pterygota, order Lepidoptera)

Family of fairly small moths which mimic bees and wasps both in colour and shape, and sometimes buzz in a similar way. Scales are absent from large areas of the wings. The thorax and abdomen usually bear wasp- or bee-like colours. Sesiidae fly rapidly and by day. Larvae often tunnel in stems of trees and shrubs. Some are pests of fruit trees. They are distributed world-wide.
