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.

Four Leopards in the garden

When I started recording Rose Tortrix Archips rosana at Bawdeswell there were relatively few records in Norfolk, and most of them were from just 2-3 observers.  I added to the pattern recording quite a few while I was there, though I see that there are now quite a few more records from a greater variety of other people too.  I didn't get any at North Elmham last year despite there being far more roses in the immediate vicinity than there were at Bawdeswell.  This year they have appeared - starting with this one on 17th July.

The best macros that night were 4 Leopard Moths.  None of them were in the trap - 3 were in the grass or on the sheet round the trap in the evening and the fourth was on the side of the shed in the morning.

Also new for the year were White Sallow Case-bearer Coleophora albidella, Burdock Conch Aethes rubigana and Small Scallop.

The caddisflies were quite good.  One species was new to me: Oecetis lacustris.

Two apparently different female Hydropsyche were the trigger for my re-assessment of the ID I've been making of these.  Initially I had a male pellucidula among numerous females, which are harder to ID.  I struggled with these as they showed one feature that seemed to fit siltalai better but in other ways were unconvincing, and although I can't recall the details one day when I had two different examples I figured out that the majority had to be pellucidula - no doubt partly influenced by the ID of the male.  Well as time went on I became increasingly uncomfortable with this ID but all I was getting was females.  Eventually I got one or two male siltalai but it wasn't until 17th when I got two different females, one of which may well have really been pellucidula and the other, like the majority of the previous ones that it resembled, I'm now fairly convinced was siltalai.  I'm still not entirely clear on these though, and won't be submitting these records without taking expert advice. Externally they've all looked pretty similar, except the worn ones that haven't shown much pattern.
