Dalgety Bay - Sarc-asm

So maybe someone will remember this lovely duo - a Pipunculid and an intriguing small calypterate taken not only on the same day but in the same sweep. I had reservations about the initial tachinid determination of the calypterate and when I whipped out its bits I was pretty convinced it was a sarcophagid. Turns out to be true, and what a tiny sarcophagid it is! I'm used to them being enormous - usually the biggest flies in any batch and longer easily than both these placed end to end. Maybe I can post a side-by-side later.

Anyway, finally I cleared the decks enough yesterday to determine that it's Pierretia nigriventris, which I thought was new for county until I checked NBN this morning. It wasn't in the Nature of Fife 2006 county list though so it's new-ish! It has a curious distribution on NBN, which seems to include about 75% of coastal squares in Wales!

Everything else is more-or-less routine apart from a new hover for me in the shape of Neoascia tenur (which may turn out to be N.meticulosa ... but still new in both cases!)

  1. You're getting more moths than me at the moment, Ali, haven't had my trap on for a few days due to cold windy weather, but it should be improving soon. However coastal East Anglia has it's own climate in the spring - any wind off the cold North Sea and it's freezing when the rest of the country is basking. Yes, I find some of the sarcs/tachinids difficult to decide which family they belong to.

  2. We have easterly chills too. I had nothing last night except an indoor white-shouldered
