A female Trypeta zoe (Diptera: Tephritidae) on a dock leaf (Rumex sp). The larvae mine the leaves of various plants including Senecio (ragworts and groundsel) but, apparently, not Rumex. See here for a more complete list of hosts.

A pair of Sicus ferrugineus (Diptera: Conopidae) mating. I hadn't noticed before that the females are sightly larger than the males.
The larvae of these are internal parasites of bumble bees (Bombus sp) and the adult females actual lay their eggs between the abdominal segments of bees in flight.
