Size estimated, and would include the folded wings. Another shot shows the abdominal appendage characteristic of a male. Interesting, perhaps, on two counts. 1-It is taking nectar. I usually see Panorpa scavenging, if I see them feeding at all. 2-It is out in spring--I see these most commonly in fall. I see we have some May and June dates in the guide. I wonder if there are different species out in the fall. I met an expert on eastern Panorpa once, I'll have to try to get him to look at this genus.

I believe the plant is Cleavers, Galium species, perhaps Galium aparine.
