A Blog for moth recorders in Bucks, Berks and Oxon
Hi Andrew, separating ambigualis (exceedingly common) from basistrigalis (not so common) is not easy and is sometimes only possible through dissection. Knowing the exact size might perhaps have helped - see my response to Adam Hartley's post on Friday 12th June.
Thanks Dave - missed the comments from the 12th and should have measured it, as I, like Adam, thought it large. Next time.
