Small Black Arches?

At light on 25 June in East Oxford garden.  This seems to match Small Black Arches - both in appearance and also flight season (it was fresh, but very lively), but I'm a bit unclear as to its status locally.

A rather busy night last night included first mass emergence of Scarlet Tiger with 29 in my single trap - quite a sight!

    Hi Ben, that is indeed Small Black Arches, a very good garden record! It is a nationally scarce species but there's a good colony in Bernwood Forest from which there is presumably some dispersal on warm nights during its flight period. I had one here in Westcott in 2013 which is a similar distance away from Bernwood in the opposite direction.

    Great - thanks. It immediately struck me as different from Least Black Arches, which I get a few of each year, but I'd been thrown by a few maps suggesting that it really was restricted to a quite a bit further south.
