Having spotted that various people have recorded both Svensson Copper Underwing and Copper Underwing I wonder has anyone ever found the larvae of Copper Underwing ? The reason I ask is that I recorded both types as adults mistakenly by using the old wing markings technique and flight times I was taught when I started in 1999. The YNU macro moth recorder Philip Winter refused to accept the Copper Underwing records (rightly, but for the wrong reasons I now believe) as he thought that only Svenssons occurred in Yorkshire. Philip by the way is the guy who first described the difference in the Palps that we all now use.
I was determined to prove him wrong as I could see a clear difference in flight times from my records or to be more accurate thought I could. The only way I knew for certain he would accept records without me taken adult voucher specimens was for me to find the larvae of both. I never found a single larvae of Copper Underwing in several years of searching despite me finding dozens of Svenssons larvae. Soon after this I stopped light trapping macros as my interest had switched to micros in the larval stages. This why I asked the question about anyone finding the larvae of Copper Underwing. Its obvious now that it does occur (I was the only one trapping seriously at that time in Calderdale so my records were biased to the areas I trapped) as many of you have seen and correctly ID both, but I would still dearly love for the larvae of both to be found in Calderdale to confirm breeding.
