I was enjoying the view from one of the barrens when a gold
and brown something came in low from the side and disappeared into the grass a
few feet in front of me. Keeping my eye
on the spot in the grass, I moved forward and crouched down for a closer
look. Nothing was immediately obvious,
so I got down on my knees and slowly began to move the dead grass leaves out of
the way. It wasn’t long before I found part
of a body.
The creature kept burrowing deeper into the grass, but I
eventually peeled away enough dead leaves to expose the full body. A Rove Beetle, Platydracus maculosus. Of all the possible beetles at Blue Jay
Barrens, I just happened to find one I knew.
I finally managed to remove enough dead grass to get a good
view. After leading me on a short chase
through several grass clumps, it now seemed relaxed. Some Rove Beetles discourage attack by releasing
an irritating chemical from the tip of the abdomen. This specimen raised its abdomen several
times, but I’m not certain that it’s a species that produces the irritant.
The Family of Rove Beetles is easily identified by the short
wing covers that leave most of the abdomen exposed. It’s amazing that the beetle is able to fold
up a fully functional set of wings beneath those small flaps. Even when fully exposed, it’s hard to get a
good look at the beetle when it’s hugging the ground. Besides the awkward view, it’s covered with
dust picked up during the chase.
In an attempt to improve viewing, I picked up the
beetle. It circled my hand a couple of
times and finally settled down after climbing halfway up my sweatshirt
sleeve. It spent considerable time
cleaning itself.
This species is a predator of insects and
other small organisms living in carrion, manure or other stinky accumulations
of decomposing organic matter. Strong
jaws overlap in front of the mouth. This
is my first encounter with this species away from its food source. It’s much more pleasant to observe the beetle
in this situation than when it’s hunting beneath a bloated Opossum carcass.
The beetle’s body is full of rich gold, browns and
bronzes. Considering where the beetle
normally finds its food, I’m not sure it’s a compliment to have this one think
my sweatshirt might be harboring something to eat. It may not always appear to be the case, but
both the sweatshirt and its occupant are regularly washed.
