The Rose Stigmellas are another pair that should be treated with caution. S. anomalella is in theory commoner, but should really be bred out to be certain it's not centifoliella. No problem with the Ectoedemia - probably on the same bush I found it there in 2006!
I've seen huge numbers of septembrella mines on some bush Hypericums in Cardiff recently - worth looking out for in urban areas.
OK, thanks Dave
