Lighting was very poor, these are digiscoped. Compared to HEGU in foreground the difference in gray is evident. Can't help but feel this could be another LBBG X HEGU hybrid. The legs are clearly not yellow in flight shots, almost seem purplish due to lighting. If not a hybrid then what could it be? Could it be a northern sub-species of HEGU? Hybrid seems more likely. P10 does have a slight bar, mirror on P9, tongues do not seem to eat into P8 too much, but hard to tell from these photos.
