A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

An uncommon barkfly, a Canary and a mystery larva

Not quite so many moths on 4th August but still pretty fair.  Among the macros Canary-shouldered Thorn and Dusky Thorn were new for the year, the Canary especially providing a dash of reality that autumn is coming - I very much think of these as autumn moths not summer-flyers.

Among the micros Apple Leaf Miner Lyonetia clerkella, Cherry Fruit Moth Argyresthia pruniella and Barred Grass-veneer Agriphila inquinatella were all new for the year for home.

Perhaps the best insect in the moth trap though was not a moth at all.  In fact I wasn't sure what order it belonged to as it was much larger than the few other barkflies I've identified previously.  But that's what it looked like and without too much searching I found a match with Psococerastis gibbosa - an uncommon species nationally.  There's a link to a distribution map in the National Barkfly Recording Scheme website and that map shows just that one square in Norfolk (near Attleborough) with a record or records of this species.  I don't suppose there are many people looking out for barkflies so I'm sure they're under-recorded, but other species show a fair spread of records throughout Norfolk so they're not completely neglected and it seems reasonable to conclude this one is relatively scarce.

Lastly here is a tiny larva that was chomping its way through a wing (of what I'm not sure - some kind of fly I think).  I've not the faintest idea what it is... let me know if you have any idea!
