Rediscovery of Earinus transversus Lyle (Hymenoptera:Braconidae:Agathidinae), a parasitoid of Trichopteryx polycommata (Denis and Schiffermuller) (Lepidoptera:Geometridae:Larentiinae)

Recent rearings of Earinus transversus Lyle (Hymenoptera: Braconidae: Agathidinae), a probably host-specific parasitoid of the threatened moth Trichopteryx polycommata (Lepidoptera: Geometridae), are reported from Britain. This braconid wasp should be seen as an important conservation target as it had not been recorded anywhere in the world since being described from unprovenanced (presumably British) specimens more than 100 years old
