Please can you help me identify this UK insect which I have never seen before.
It is approx 12mm long and was found near RG10 Reading.
That's the beetle Metoecus paradoxus. It lives in wasps nests nd the larva parasitizes wasp grubs. Widespread but not common, I have only ever seen one.
Thanks Clive. That all fits, I have a wasps nest above my bedroom window, the wasps are somehow getting into the room along with the beetles.
