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.

Spruce Bud Moth

2nd August was another good night.  A couple of moths were species I have rarely seen before:  Broad-barred Knot-horn Acrobasis consociella was only my second while the scarce Spruce Bud Moth Zeiraphere ratzeburgiana was my third.

2 White-triangle Buttons Acleris holmiana were new for the year.

Pale-streak Grass-veneer Agriphila selasella and Scalloped Hook-tip were also new for the year for home.

This Dotted Grey Groundling Athrips mouffetella was suspiciously similar to the one I trapped a couple of nights earlier - I guess it was the same individual.

This Ash-coloured Sober Acompsia cinerella wasn't the same as the one I had recently.

I'm still trying to sort out how to identify Agonopterix ciliella.  I thought this one was a good candidate being large and dark, though it lacked much in the way of pinkish tones underneath (just a bit on the legs).

The hindwing showed a very strong pink flush to the cilia around the apex and five fusous bars through the cilia.  Not as distinct as some ciliella can be and so still not a firm ID, but at this point it's looking hopeful.

The genitalia are very similar to the very much commoner heracliana, but there are supposed to be differences.  To me this one's bits look exactly the same as every other male Agonopterix heracliana I've examined.  So either it was heracliana, or the genitalia of ciliella are harder to separate than various texts suggest.  I await a clear and undisputable ciliella to compare, but in the meantime am increasingly suspicious about how accurately a lot of records of ciliella have been identified.

 Agonopterix sp., North Elmham, 2nd August

One curious thing if this was just a Common Flat-body Agonopterix heracliana is that of all the ones I've examined (scores now) the large dark ones have also been the ones with the best looking hindwings.  But I'm yet to find one with 5-6 really obvious dark fuscous bars on the cilia... maybe when I do I'll be able to spot the differences in the genitalia.
