What is this thing?

I have taken many (many) pictures since I quit using film cameras, since electrons are so much less expensive than film stock. Some of those pictures have been interesting to look at, partly because they were unusual subjects, or extreme close ups, or had the context removed from the frame, any other reason. I'm sure you've all seen such pictures. I have fun looking at them and guessing what they are. Maybe you'll have fun guessing what these are.
