Hello, I am having trouble determining this Tachinid. I keep keying it as Ernestia spp, but the specimen does not fit any of the descriptions in Belshaw. The parafacial area has fine dark hairs over its complete length. Any suggestions welcome - is it even Ernestia? Taken in my garden in Shrewsbury, UK 17 May. Length approx 9mm.

epicampocera succincta without any doubt. Don't know where Belshaw gives you trouble. Theo |

Thanks Theo. I'll run it through Belshaw backwards and work out where I am making the wrong decision.

I reviewed the specimen of Epicampocera succincta and found the couplet in Belshaw that caused me a problem was the one asking whether or not the mouth edge is obviously projecting beyond the base of the vibrissae. It's the interpretation of what is obvious and what is not obvious that caused me aproblem, as the mouth edge certainly projects beyond the vibrissae in my specimen and to me it was obvious. Others may want to mark their Belshaw's at this couplet (it's about couplet 39) to flag up the possibility of mis-interpreting this feature.

I agree It is obvious in both, but in Ernestia, it is more obvious, to semiquote George Orwell. In direct comparison it really is obvious, however, this does not help the beginner. Theo |

The worrying thing is I have seen a good number of Epicampocera before - I suppose I'll eventually just learn to recognise the genus.

Good clues are: bluish shine (also in Pales) black, clavate palpus (esp. female) distinctly curved outer edge of third antennal segment shown in first pic Theo |
