Common but Confusing
No.1, a colourful version of Acleris laterana. Or is it the Strawberry Tortrix A. comariana? The red markings would seem to be consistent with the latter name. Fortunately the recording sheet I use permits the grouping of the two species together, thus avoiding the need for a decision!
Few groups of moths causes me more consternation than the Crambids, and there's no avoiding the decision with them. Sure, there are one or two species such as Eudonia pallida and E. delunella which are easy to name, but for the most part it's the three common ones I encounter here: Scoparia ambigualis, Dipleurina lacustrata, and Eudonia mercurella. I think. Take the three examples above, all caught last week. 2, I would name S. ambigualis, but isn't it a bit late for that species? Could it be E. truncicolella? 3 and 4 are much darker, it's late summer, surely must be E. mercurella? But the book (S&P) says 'E.mercurella never has any yellowish brown on the forewing'.
Confusion reigns! I need to go on a Crambid course. Any volunteers to hold one?
