Hi, Jim

All the best, Mick

Yep, E. balteatus. This species seems to have had a high proportion of melanic specimens on the wing this year if my experience is anything to go by. Odd weather conditions? Worries over Northern Rock? Who knows

Ithought that is what it would turn out to be - nothing else seemed to fit!!
Thanks for help.

The key with this is that E. balteatus is very sensitive to temperature and this one looks to have developed under quite cool conditions

Regards

Roger
