Tropisternus lateralis
There's another western subspecies which I can't recall at the moment-will have to check the books. Anyway this one doesn't look like T.l. marginatus.

Thank you Brady! ...
... for placing this beetle in the correct family!

I am hoping that snowy and rainy weather lets up a bit - soon! The porch light bugs are mostly not to be seen in this weather.

Hydrophilids can be sneaky so
Hydrophilids can be sneaky sometimes -- watch for that antennal club.

I'm a big fan of rain and all, but I think even I've had my fill this year. I suppose I'd feel differently if the rain beetles were still flying. I haven't even bothered running my mercury vapor yet. I think next week may be the end of the rainy season for us. We shall see.
