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.

A saltmarsh species in North Elmham

29th July was another good night with 516 moths of 128 species.  The highlight from my perspective was my second ever Sorrel Bent-wing Opostega salicella.

Another nice addition to the garden list was this Mottled Marble Bactra furfurana.

North Elmham, in the middle of Norfolk, isn't renouned for its saltmarsh species, so a Saltmarsh Bell Eucosma tripoliana was quite a surprise.  This species does turn up inland occasionally - I had two together at Bawdeswell once and at the time I recall Jon mentioning that he'd had them at Hindolveston a couple of times too.  Even so, a very good one to add to the garden list.  I don't recall the weather on the night but looking it up it seems like there was a light northerly breeze during the night, so perhaps this helped move this individual down from the coast.

I didn't realise the identity of the above Eucosma until I dissected it, though perhaps in hindsight I should have at least suspected it at the time.  I thought it might be Bright Bell Eucosma hohenwartiana.  In an odd twist there was a Eucosma hohenwartiana among the moths I retained, but an unusually plain individual which I thought was a Bactra species!  Obviously I wasn't having a very good morning when I looked at these!

Other goodies among the micros included Body-marked Case-bearer Coleophora clypeiferella and another Plum Fruit Moth Grapholita funebrana.

Although most of the excitement was with the micros there were some noteworthy macros too, inlcuding my first Sallow Kitten here this year and another Bordered Pug.

It was another good night for Footmen with 15 Rosy Footmen, 39 Dingy Footmen, 18 Scarce Footmen, 3 Buff Footmen and another count of 76 Common Footmen.  This rather tired-looking individual was tiny - perhaps 60% the size of a typical Common Footman.  Can't see that it can be anything else though.

I mentioned the 2 Dichochrysa prasina (Green Lacewings) at the end of my post for 28th July and apart from those there wasn't a great deal of non-Lep interest in the trap.  Bugs were represented by my first Forest Bug (aka Red-legged Shieldbug) of the season and bettles by a Brown Chafer.

On the outside of the trap was this slug.  I've attempted to identify a few slugs this year but am struggling a bit.  I think this one is probably a Great Red Slug Arion rufus, but am not sure if I can rule out the red form of Lusitanian Slug Arion vulgaris, or possibly other Arion species.  Any clues would be appreciated...
