15th June this year, dry grassland on shingle. I've been trying to run this through Belshaw and come up with Nilea hortulana (though not with a great deal of confidence). Does that look about right?

It is quite likely Nilea, have you ruled out innoxia? Jaakko |

Thanks Jaakko. The only Nilea on the British list is hortulana at the moment, so that makes life easier. Looking through the keys again, one thing that does confuse me still are Belshaws 'reclinate bristles on the parafrontal' and Tschorsnig's 'oi', which should be one for Nilea, and which I think I can see two of!

Hmm.. I don't have any keys with me, but if it has 4 st, it should be Tlephusa cincinna. Are the palps black(ish)/not yellow? |

It has strikingly pale palps and three st. If I run it with two oi it comes out as Huebneria affinis. |

It does look like it has 2 reclinates so perhaps it is Huebneria? It is a very rare species in the UK but you had one a while ago that we both agreed was Huebneria so it is possible  When I visited the NHM a few weeks ago they didn't have any UK specimens

Aah, was that the specimen I gave you at the tachinid course at Preston Montford the year before last (I never found out what that was)? If it was it explains the sense of deja vu I had while keying this one! This will be one for you then I think. Aren't you running an id day early next year? I could bring it to that if you are, and I also have some other stuff I have puit aside to send to send to you. |

Hi Chris - yes I think we are doing another workshop - they'll get sick of the sight of us soon, I think!  One day we might actually have to finish the book too - though the finishing line seems as far away as ever - the key is up to date though - I'm doing that bit! Bring the latest Huebneria along and if you remind me before the date I'll bring the 2 specimens I have here (your first and the one I have from Russia).

Will do Chris. Could you give me the date and grid reference for the Preston Montford specimen so I can stick it on our database? |

Hi again, Hubneria affinis (note the spelling) is plausible, especially if the apical scutellars are erect and there are only three humeral bristles. They can be locally quite numerous here and by far the most common tachinid reared from any mid-sized to large arctiid moth. Collect some Parasemia plantaginis, Phragmatobia fuliginosa or Arctia caja larvae in the spring, I'm sure you'll get out at least some affinis. I finally managed to send a parcel to Theo, so maybe I will get around to send one to Chris as well... I could include some affinis as well. |

Thanks for that Jaakko. The apical scuttlellars are erect (about 45 degrees) and there are only three humeral bristles, so it's looking promising. A real feature of this place early in the year are the number of arctiid larvae we find moving around, so I will give rearing some of them a go. |

Thanks Jaakko - all donations very gratefully received!  Huebneria is an unusual species because in Europe it seems fairly easy to find but over here we had just two records until recently. The NHM in London has lots of European specimens but the only UK specimens are at Oxford University Museum. Consequently I have never felt very confident about keying UK Huebneria so I held back on publishing Chris's record but recently I have become quite sure that it is correct

But I had a look through the NHM specimens and they show quite a wide range of variation so I think the ID is good. It should really be published so perhaps you can write-up both when we have confirmed the second one?

Here's a Hubneria affinis reared from fuliginosa, Ab:Lieto, Southern Finland, spring 2008. About the nomeclature (Theo might have a different opinion): The original is genus name is Hubneria (R-D), but as it refers to the famous naturalist (not naturist) Hübner, the spelling was later corrected (by Herting, if I remember right). Might be linguistically more right, but anyways against the code. Jaakko attached the following image:  [128.93Kb] |

Yup - the 2 I have here look like that too. Orange scutellum with erect, short apical scutellars; and the abdomen has lots of erect bristles and hairs or the dorsum - and only 3 bristles in a line on the humeral callus

Hmm, that grid reference is not the same place as I collected the specimen (should be TQ934174). Does the data card say Rye Harbour NR (and have my name on it!)? |

Hi Chris - It's certainly one of yours from Rye Harbour NR but the grid reference is handwritten and on second thoughts the first number could be a 9 - making it TQ945186 - does that sound better?

Phew, thought someone else was gonna get my glory there! I'll have to check my archived notebooks for the exact spot, but that is the grid ref for my garden (and not to far from the current specimen) so I suspect that I had it in my head that it came from somewhere else on the reserve, hence the confusion. I'd be very happy to writre this and the current record up, and I guess we can chat about it at the workshop. |
