Heat wave mystery

January 12, 2020  •  Leave a Comment

Years back, when we had a break in the cold known as the January Thaw, I'd make a trek to the bridge over the nearby Green Falls River to look for stoneflies: hardy insects whose aquatic nymphs would turn into adults that emerged from the water during above-freezing winter days to creep along the metal bridge railings in search of potential mates. These days, there's hardly anything to thaw in January, but there are still stoneflies to be seen. With the temperature this afternoon topping 70 in the sun, the Plecopterans were certainly out, but so were some unexpected beetles. This tiny creature might be a Rove beetle, one of those coleopterans whose elytra don't cover the abdomen. I couldn't, however, come up with an identification I was entirely comfortable with, so all I can do is keep looking for the identity of a minuscule member of the beetle corps with rather natty... and short... red-spotted, black wing covers.
