Out of interest, how does one

Out of interest, how does one differentiate this from B. anglicus?

hortulanus

My picture from this morning.

anglicus has the vein r-m slightly longer than the base of vein R4+5, which is very different to hortulanus. You can see the very short cross vein r-m of hortulanus on my pictures. It is not clear on yours, but the whole appearance of yours and the time of year are right for hortulanus. hortulanus can be quite a lot bigger, too.
