Saw something hurrying across the road, and pulled over to get a photo. It's a Sphecid wasp, dragging the grasshopper's she's caught and mostly paralysed. She was fast, too - by the time the camera had focused on her she'd already run out of shot, even from standing height.
Sphecid wasps are also useful examples in arguments about intelligence and free will. Because even wasps with very complicated and apparently purposeful behaviour, like Sphex, are still really, really dumb. They're incapable of improvising, realising that they're repeating things they've already done, or counting how many prey they have stored. This quality is called sphexishness.
