At Finemere on 1st June I ran two MV lights at different spots along the main ride. Both performed as well as expected in quite reasonable conditions, one bringing in 85 species and the other 84 for a combined total of well over 100. There were no surprises but I was pleased to see a rather late Great Prominent having thought, with the lock-down, that it was a species I probably wouldn't record in 2020. Tortrix viridana was just starting to appear although there was no sign yet of Archips xylosteana (and just the one crataegana). Those three will be swamping the traps there in two or three weeks time. Blotched Emerald was already out in some numbers, as were Heart & Dart and Straw Dot, but there were few other moths in any numbers apart from Common Swift, Light Emerald & Treble Lines. It was good to find Cream Wave, Grass Rivulet, Sloe Pug, Small Seraphim & Brindled White-spot, while Crassa tinctella may be new for the site's already extensive moth list (I've recorded about 670 species there and the site list stands at more than 700).
At Howe Park Wood on 2nd June I ran three MV lights. Here the results were rather disappointing despite similar weather conditions to the previous night. The best performing trap brought in 46 species, while the other two managed only 29 and 39 respectively, a decidedly poor result for the beginning of June although the overall total came to around 80 species. Poplar Lutestring and Purple Clay were nice to see but there was little else of any note. As at Finemere, Light Emerald and Heart & Dart were around in some numbers but here they were surpassed by Silver-ground Carpet. The only other species to appear in any numbers was Ingrailed Clay in its many different forms.

And in case it helps anyone else with this species which regularly causes ID problems, here are four quite different-looking forms of the extremely variable Ingrailed Clay from Howe Part Wood. It is sometimes difficult to believe they are all the same species!
