Message to Ian:
Another unidentified insect inadvertently included in a botanical picture. Any idea what it is?

Message from Ian:
It is Eriothrix rufomaculata, it has no common name.  It is one of the of the Tachinidae family – parasitic flies. They are fairly common and widespread throughout Britain.
Adults are active June to October and are flower feeders, the larvae are parasitic, developing inside the larvae of moths, especially Grass-veneers, tiger moths and lappet moths.

  1. I find it difficult to sympathise with the parasitic larvae eating through a tiger moth caterpillar – I know we shouldn’t have favourites but I would rather have a tiger moth than this bristly horror.
