In the bottom of one pit I spotted an ant that had lost its footing on the steep pit sides and had fallen victim to the lurking jaws of an antlion.
Here is a close-up of the antlion's prey. I could catch glimpses of the antlion's appendages as it moved the ant around.
Here is a photo of an antlion that I exposed by gently blowing away the sand in the bottom of the pit.
Usually the antlions are hidden under the sand in the bottom of their pits awaiting some insect that might fall into their trap, but here the antlion's jaws are visible as it lies in wait.
Even winged insects can be trapped in an antlion's pit-trap.
We blew away a few sand pits in hopes of finding some antlions to photograph and in the process found some antlion pupal cases.
