Dolichovespula media (Retzius, 1783) – Median Wasp

Unmistakeable species due to almost completely yellow ocular sinus – a colour feature not shared by any other Central European species of Dolichovespula . Queens are very similar to workers of Vespa crabro ; both species can be separated by distance of ocelli to margin of head.

Probably the rarest social wasp excluding parasitic species. It sporadically occurs in the whole territory of the Czech Republic and Slovakia from lowlands to mountains. A forest species.
