Worminghall, Bucks Update

The year list here is now on 381 (about 50 species less than this time last year). Last night was the best night in a while with 86 species of 250 individuals. Very few migrants this year (particularly in recent weeks). 

A few photos below of some interesting/ uncertain ones (sorry for the sudden influx). Any help with the identifications much appreciated. 

Marbled Mompha, Mompha propinquella ?
Base-lined Grey, Scoparia basistrigalis ? 
Can this be identified as anything other than a Dichrorampha sp ? 
Water Plantain Conch? 
Bactra sp? 
Parsnip Moth?
Acleris schalleriana?
Aproaererma anthyllidella?
Pammene sp? 
... and one macro, Maple Pug?

    Hello Peter,

    Of the micros, the three I'd be happy to accept from those images are Mompha propinquella, Bactra furfurana and Aproaerema anthyllidella. The last one of those three should really be dissected but the posture shown in your image makes it clear to me that it isn't Oxypteryx atrella which is really the only species we have locally with which it could be confused.

    Of the others, the scoparid is too worn to name and in any case doesn't look right to me for basistrigalis. The Dichrorampha is more than likely acuminatana but would need dissection at this time of year (the Spring generation is safe to name, when there are no other candidates around). I've no idea what a Water Plantain Conch is but the moth looks like a Gynnidomorpha species which again would need dissection. You might be correct with the putative Depressaria radiella (Parsnip Moth) but to me it actually looks closer to chaerophylli so is another where dissection would have made things clear. The Acleris seems a little too bright for schalleriana and the shape doesn't look right to me, but unfortunately this example has lost scales across the middle of the wing which might have helped work out which of the others it might be. Finally, the Pammene image is simply not clear enough to come to a decision.

    I'm rarely happy doing pugs from images, but at this time of year (and assuming the size fits) your example could realistically only be Slender or Maple and there seems to be an acceptable hint of brown scales on the forewing to suggest that Maple is correct.

    Thanks so much Dave. Yes sorry Water-plantain Conch is G.alismana. I'll amend these records in iRecord too. Thanks again.
