This is neither the greatest technical quality nor a great composition, but I figure it's OK "under the circumstances".
I was sitting at my computer last night when I observed some small speck of black moving across a piece of paper on my desk. I had no clue what it was, so I hauled out a 10X magnifier and took a look. To my surprise, I saw a tiny wasp. So I briefly trapped the wasp under a glass while I assembled some photo gear. Then I removed the glass and shot like crazy while the critter scurried around. This is the best I got before it disappeared entirely.
To understand the size of this beast, consider the very low key scale that I photoshopped onto the background from shooting a ruler after the wasp left. Those are 1 mm tick marks, so yep, this critter was less than 1/10" total length, from the tips of its antennae to the ends of its wings!
The background, by the way, is polished oak sitting under a clear plastic desk protector. You can see a few scratches on the surface of the plastic.
Canon T1i camera, Sigma 105 mm macro lens at close focus plus 68 mm of tubes, a bit over 2X on sensor. This is a substantial crop, showing a little more than 1/2 of the original frame width. ISO 100, f/8, onboard flash with small aluminum foil snoot and tissue diffuser.
Noting motion blur on the hind leg even with flash exposure, I guess this critter was moving pretty good at the time!

While at work Friday, a small wasp of unknown identity to me, landed directly on a yard or two of white cloth fabric that I was working on. A female it was and ever so tiny as not to be seen had it not landed on the fabric. The boss would have just loved my enthusiasm as it bubbled over upon me, in getting the wasp on my finger tip to show everyone nearby my workstation.
