DIGLYPHUS isaea
parasitic wasp
Duration of
development; egg-adult, at 20șC ± 16 days.
The parasitic wasp lays its eggs in or next to leaf miner
larvae of the second and third stage. The young parasite
larvae hatch from these eggs, and will then feed on the
body fluids of the larvae. The diglyphus is used in late
spring.
