Default beetle behavior

So, suunto or others, why do beetles, on flowers or elsewhere, randomly wave their back legs in the air? I have seen it on multiple beetles on flowers, usually as they are slowly walking across the surface. Here are photos of what I mean.

I've seen bees do that when you pet them. Their way of pushing you away?

Except the beetles seem to do it when they are just sitting on the flowers, minding their own business. So you pet bees, too? My husband taught my daughter to do that when she was about five, which worked great until the first time she was stung. It takes a gentle hand.

My daughter, who is off to Columbia University's graduate premed program in the fall, says that her very earliest memory is of me patting a bumble bee. I seem to remember her being two, going on three, at the time. I was, of course, attempting to insure she would not be one to fear bees. It worked, although she also remembers, at the age of about four, getting nailed by a yellowjacket while picking blueberries.

So maybe they are waving their legs around, hoping they look like wasp forelegs? Perhaps. I don't have a better explanation, though I am not sure that makes complete sense. It may be one of those mysteries of nature.
