Back into moth recording

Late May, and while the weather is still a bit chilly due to cold winds, I noticed moths coming to lit windows and decided it was time to carry out one of my aims for the year: get back into moth recording. With my parents visiting, I hoped I might find something interesting for them to look at.

It turned out that there wasn't much in the trap when I got up at the crack of dawn. In some ways, this was a good thing; a big catch to work through would have taken a long time, especially as my identification skills are so rusty. On the other hand, the few moths here compared to the number and variety I had back on the farm is a bit depressing.

The results, in 2013 checklist order since I need to get back into good recording habits!

70.054 BF1727 Silver-ground Carpet Xanthorhoe montanata : 2
70.226 BF1906 Brimstone Opisthograptis luteolata : 3
72.020 BF2060 White Ermine Spilosoma lubricipeda : 1
73.002 BF2449 Dark Spectacle Abrostola triplasia : 1
73.032 BF2425 Nut tree Tussock Colocasia coryli f. medionigra : 1
73.102 BF2302 Brown Rustic Rusina ferruginea: 2
73.329 BF2102 Flame Shoulder Ochropleura plecta : 5

23.5.18. 15 moths, 7 species. (Wot, no micros? - Ed)

I only realised I had a Dark Spectacle (rather than The Spectacle) when I looked at my photo and saw the cross-lines edged with reddish-brown. The moths I puzzled over were the Nut-tree Tussock and the Brown Rustic. The latter was because, after a late spring, could I really have Brown Rustics in late May when they normally appear from June? But the white marks on the leading edge of the wing and the cross-lines are the key and this male is quite fresh. I must look out the stones and slate I used to use for taking moth photos, although my thumbnail gives an idea of scale.

As beautiful and accurate as Richard Lewington's illustrations are in the Field Guide, I don't think they do the Nut-tree Tussock justice, as it's much fluffier and more beautiful in real life. I thought I'd seen it before, but couldn't think what it was and initially looked at the Tussock moths, which are in a different family. The word 'tussock' niggled at me and a scan down the index and through the illustrations confirmed the identity of my lovely visitor.

Having managed to ID everything (eventually), I feel less daunted by my rusty ID skills. Bring on the next session!
