Here is my first observation of the Checkered Beetle species.
I have observed a few of them in an area of forestry work, on recently cut oak stumps.

The pale colour of the tree stump gives a nice uniform background.
I have also used the tree stump as a support to quietly adjust the focus and the exposure parameters with no risk of moving blur.

Here is one Checkered Beetle with a prey.
I am just wondering if we can tell which species is the prey.
