Answer to the Monday Night Mystery

What was that odd squishy-hairy thing in yesterday's SEM?

It's the tip of the foot of a muscid fly, showing the adhesive pads (called pulvilli) that allow the fly to cling to surfaces. Here's a slightly less magnified view:

Points are awarded as follows:

-Two for JasonC., for being the first to pick that it was a foot of some sort.
-Five for Jim Harrison, who bagged the organism.
-Two to Gunnar for guessing the empodium, which is one of the structures visible in the image.
-Two to Roberto Keller, for providing more precise technical detail than that given preceding guesses.

update Boy, am I ever a jerk. Adrian gets 4 points, which I tallied and then neglected to copy onto the list. Must be because I'm primitive.
