One of the most amazing things I’ve EVER seen! While holidaying recently on Lewis and Harris, we had lovely walks (despite the weather) in Aline Community Woodland, where we spotted several “colonies” of Puss moth caterpillars on Willow. Looking more closely at several, I was amazed to see Scottish midgies,Culicoides impunctatus, feeding on them, then spotted one festooned with them, counting 29 on one side alone. Have cropped in (see second image) to show one of the midgies engorged with “green”, whatever the equivalent to human blood is. Wow, who knew?
