Description:

Pretty sure this is an aphid, on close inspection it has slightly swollen cornicles, 6 antenna sections and no 2nd fork off the median wing vein. It is black/dark blue-green and has lighter markings on its abdomen (colouration and markings don't show up well in pictures).

Information on species

I cant help with identification, but I suspect the maps on the NBN reflects lack of aphid data on the NBN and so the map is not a true reflection of the abundance of the species. Aphids are the realm of plant pest research etc rather than natural history sites and the species data may not have been shared. This site has info on the species. The bird cherry is only the overwintering plant (and according to the article is increasingly not essential); the species feeds and is a pest of cereals and grasses. http://www.rothamsted.ac.uk/insect-survey/STRhopalosiphum_padi.php

Have you tried -

trawling the Bioimages web site? Google "aphids bioimages": might be worth a look.

Not R. padi

difficult to pin down which aphid species this is, but I'm fairly certain it's not R. padi. The siphunculi and antennae too big - see http://www.biolib.cz/en/taxonimage/id154776/ for an image of an alate for comparison
