An Exciting Grass-moth

Yes, that's not an oxymoron, there is such a thing!  The one moth of interest in last night's garden catch was this Agriphila latistria.  The books say it is confined to dry, sandy habitats particularly around the coast but this is the second individual I've had in the garden here where we are a typically damp area on heavy clay.  The previous example was caught almost two years ago to the day (28th August 2016).  That was a first for VC24 Bucks and I'm not aware of any subsequent records.  So keep checking those tristellas - you may find this amongst them as well as Agriphila selasella which is having a good year too.  Agriphila latistria is noticeably "different", having a whitish head and that broad pure white band stretching right to the fringe at the termen.

  1. Wot, no Agriphila geniculea? Big numbers of these every night here in Chorleywood.

    1. A. geniculea was the only grass moth I trapped last night, 25. I also had 8 Straw Underwing, but no Heart & Dart - interesting how different sites differ.

  2. For some reason I don't get geniculea here in any numbers at all (between 5 and 20 individuals per season is the norm and I've had a grand total of four so far this year).

    Not that it really matters, but I've just realised that on my list above I failed to add in those moths left on the sheet when the trap was brought in at 5am and they included two additional species: Agonopterix alstromeriana (1) & Lesser Treble-bar (2).
