Beetle-killing Wasp (Tiphia femorata)

…a species of Tiphiid wasp which occurs through most of Europe, the eastern Palearctic ecozone, and North Africa. Adult T. femorata can be seen flying from June through September, feeding on the nectar and pollen of flowers. True to their common name T. femorata are noted parasitoids on beetles (Typically members of the Scarabaeidae), with females locating their larvae and injecting their eggs inside them to develop.

Winged male Yellow Flower-wasp, perhaps Agriomyia sp.

The female flower-wasp has no wings and her legs are modified for digging. Being parasitic, their eggs are laid within beetle and bug larvae which must be dug for.

As the female must still eat nectar, it is common to see the male and female attached, in prolonged mating behaviour, which the female takes advantage of to feed.
