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.

Silver Hook and other Surlingham goodies

Church Marsh, Surlingham was the destination for Norfolk Moth Survey's last night-time moth event in 2016 and I was keen to go along to this one, a site I've never visited before.  It was a windier night than we would have liked and it was a little difficult finding a site sufficiently sheltered.  We did the best we could and it turned out to be a thoroughly worthwhile night.

The star of the night was undoubtedly a Silver Hook - a scarce wetland species with its Norfolk stronghold in the Broads.  Perhaps surprisingly though, it has only rarely been recorded in the Yare Valley, and not since 1985, so this was a very pleasing result.

I was also pleased to see another Broads special, especially after missing one that was recorded by others at the last event at Claxton Manor - my first Reed Smudge Orthotelia sparganella.

A third lifer for me was the tiny Sallow Pigmy Stigmella salicis.  It is sometimes said that these Stigmella are too hard to identify with certainty to record as adults, and that there is no need to anyway as their mines are so easy to find.  Well for no logical reason I like to see adults before counting them, and I like a challenge, so I set about trying to resolve this one using the excellent Kleine Vlinders key.  Where a couplet was in the slightest bit equivocal I followed both options until I reached a dead-end on one, so I'm fairly certain I arrived at the correct ID - and I'm pretty sure there was a lot of its foodplant present too.

Although Common Marble Celypha lacunana was suggested as the ID for this moth I don't recall seeing one quite like this so took it home to confirm.  Whoever called it that (Ben I think) was spot on.  There was a normal one too.

I was also slightly doubtful about this rather dark Flounced Rustic, although by the time I came to dissect it I had already convinced myself that was what it had to be - and I've seen a couple of similar ones since so perhaps it wasn't so odd after all.

A Scorpion Fly proved to be Parnorpa germanica and although I can't remember what we thought at the time I think this beetle must be Great Silver Water Beetle (though open to contrary suggestions).
