Ilybius discedens (Sharp)
Based on distinctively small size and locality data. Similar sized
I. vittiger
can be separated by range (it is a far northern/arctic species).

Ilybius most likely...
most specimens have the pair of subapical spots on the elytra..but one needs to look closely at the metatarsal claws to be certain

Found in California
My son was out on our trampoline with a neighbor about 7pm when a huge beetle landed on his foot. He carefully caught it in a cup and I promptly took a picture of it so we could find out what it was. Where we live we have never seen anything like this diving beetle (acilius) before. I suppose it was looking for a water knoll to land in and was sorely disappointed when he landed on my son's foot. We are very intrigued in this 2 inch critter. Anyway, a happy ending came when I freed it to our grass upfront. (4-4-07)

Probably not a Whirlygig...
At least from what I've seen. Most whirlygigs have very small back legs, with the front legs being longer and more grasp-like. But my vote is that it appears to be some sort of diving beetle. A
Water Scavenger
perhaps?

Not Hydrophilidae, either:-)
Have to admit I was initially fooled, too! This is a dytiscid, or "predaceous diving beetle." The long antennae are clearly visible. In hydrophilids, the antennae are short and clubbed, but the PALPS are long, and often mistaken for the antennae, which is what fooled me here. Dytiscidae. My final answer:-)

It's in the name
Or it's in the legs! It is the front-leg locomotion of the whirlygig beetle that causes it to be able to spin on a dime this way and that like a whirlygig.

You have some excellent shots
You have some excellent shots of a Water Scavenger, and that's probably what mine is too. Thanks Tony.
