Moths began coming to the Skinner as soon as it was switched on and from then until it was switched off, at 02:55, there was a steady stream of them. As well as the midges, the other unwelcome presence was thousands of tiny mayflies, which descended on the trap, only to then die and glue themselves to every surface. The same happened in May 2015 and having collected specimens, it was identified as Caenis rivulorum, by Steve Omerod and Craig Macadam.
Being one of the national Moth Nights, this year's target was the Hawk-moth and we did indeed have two species: nine Poplar Hawk-moths and seven Elephant Hawk-moths. We had a total of 36 Diamond-back Moths, but they were the only migrants.

The final score between the two traps was 84 species, with a couple still unidentified.
Martin and I were finally staggering out of there at around 03:45 and when I got home at 04:00, I didn't bother going to bed.
Apart from the moths, as always, there were other points of interst. Earlier in the evening, Martin Bevan had mentioned mysterious holes in Hogweed leaves, so after he had gone, when going to check on the Heath trap, I spotted some small Hogweed plants with holes in their leaves. Turning them over, I found the culprits; these small beetle larvae. As a result of a quick online search, I think these may be the larvae of the Celery Leaf Beetle (Phaedon tumidulus), but stand to be corrected.

All in all, it was a good and productive night and nice to have the company and assistance of the two Martins and Chris.
My particular thanks go to Martin Bell, for staying the whole night and helping me sort out the catches and pack up the traps. Cheers, Martin; much appreciated.
