Saw this beautiful big click beetle on the deck a few days ago, about
an inch long. If clicked away after one picture, disappearing into the
brush.

The two black spots are fake eyes that startle birds and
other predators and give the beetle a chance to get away. Lots of
butterflies and caterpillars have fake eye spots for the same reason.

Click beetles move by suddenly snapping their body at the middle —
they do that by pulling a peg on the thorax out of a tight groove, sort
of like pop beads. When they do that, their body flips away,
accelerating faster than any other animal on the planet. They don’t go
very far, especially the little brown click beetles that are so common.
But this Eyed Click Beetle moved fast enough to get away from me and my
camera. I couldn’t find it again.
