We have had distressingly few bugs of many sorts this year, I think because of a late freeze. My garden, which is normally swarming with pollinators, has had almost none so far, and the mountains where I walk had very few as well. But one genus that seems to have done remarkably well this year is Chrysops, parasitic flies that are called "deer flies" on this side of the pond. Once they find you, they don't give up, and I don't think I can recall any year when they have been as much of a nuisance. However, they are remarkably attractive, if you ignore the saw-like mouth parts. Here are two different species that are both abundant where I was last week. The larger, orange-bodied species goes for your head. The smaller black ones like ankles too.
C&C welcome, of course.
