Ephydrid Flies

A pair of flies mating, probably Notiphila riparia (Diptera: Ephydridae).  I saw a lot of these (about 50) swarming on a bush on the north shore of the large lake.

Tephritid Fly

Tephritid fly Goniglossum weidemanni (Diptera Tephritidae) on bryony (Bryonia dioica), the host plant for its larvae.  Lightly dusted with yellow pollen.

Ant-Mimic Wasp

A wingless wasp that mimics an ant: probably a female Gelis sp (Hymenoptera: Ichneumonidae).  There are about 70 species of Gelis on the UK checklist (see here) so I don't hold out much hope for determining the species.
