My back yard is overrun with tenebrionid beetles (genus Eleodes), aka stink beetles. This is in Southern California, early May 2010. My wife Kathy is behind the camera making comments from the peanut gallery.
Here is a picture of a larger version I took a couple years ago:
This was a good sized female who was a little worse for wear (note the dent in her elytron/back). She was ovipositing in a dirt road.
Here are a couple of great videos that I encountered via different sources within minutes of each other. Both demonstrate cooperative hunting and problem solving in toothed whales (Odontoceti). The first, pointed out to me by my mother, is a beautifully photographed and (as always) nicely narrated by David Attenborough, clip of bottlenose dolphins (Tursiops) working together to create silt nets by hitting their tail flukes on the sea floor which they use to corral fish into a tight group.
