Its the wrong clearwing!

I went to Dunstable Downs today to try and get some clearwing records for the site using pheromone lures. My targets were Orange-tailed, Red-belted and Six-belted. I failed on all three but the VES lure which is used for Orange-tailed attracted a male Yellow-legged Clearwing instead. This is the species the lure is made for but it was still a surprise to get one at this site as it is a species of Oak stumps. The closest record is from Sewell Cutting in 1978 by Vic Chambers - also an odd site for the species.
