This is a different female, collected a month earlier on 22 July 2006, in the same east London cemetery park. I see that Stubbs says that the easiest way to distinguish E arbustorum and E abusivus is to check that the mid tibia is clearly bicolour (arbustorum) and not entirely pale (abusivus). Is this character reliable?
