I donated

Just a silly little graphic I made for a friend coordinating a blood drive … with the idea that a sticker might be made for donors:


I also wrote a silly little blurb, though I’m sure the math could be improved upon:

“Some people might be hesitant to donate blood if they haven’t done it before, so I just wanted to remind everyone that they have, indeed, donated blood before: to mosquitoes. A typical mosquito (always a female, by the way) flies away with 0.001994 mL per meal, at least according to an article from 1937 on blood loss in horses.  Not so much, perhaps, but it adds up when her friends find you, too, and they do.  So you’ll donate a pint of blood after being visited by 237,212 of the little beasties.  Much easier to just sign up and be done with it in 10 minutes.  And it won’t itch when you are done!”

Copulating robber flies, with snack

Two rather large (almost 2″) robber flies mating on rabbitbrush in Madras, Oregon.  Male has a longhorn beetle (perhaps Crossidius hirtipes?) as a nuptial gift. I don’t know the species, unfortunately.
