orange-spotted bark-gnawing beetle - Tenebroides bimaculatus

orange-spotted bark-gnawing beetle - Tenebroides bimaculatus
Nashua, Hillsborough County, New Hampshire, USA
July 9, 2006
Size: about 5 mm
This handsome little trogossitid came to my mercury vapor (MV) light Monday night. I don't see an obvious name match in the New Hampshire checklist (such as bimac*ulata :-), so I'm wondering if this might be a new arrival in the state.

My mot*h sheet came out of the washer with a big rip in it and I had done nothing about repairing it, so I hung the MV light in front of the white garage door, with a piece of Tyvek house wrap along the bottom in place of the skirt. As it turned out, few of the visitors clung to the garage door; most were on the horizontal Tyvek. A few stragglers, including this beetle, were off the Tyvek. This one was nestled in a depression in the asphault driveway. I had to suck hard with my brand-new aspirator (BioQuip.com) to get it to lose its grip.

Unfortunately, my time on my knees on the driveway might have caused the next day's development of a painful pre-patellar bursitis the next day and I did not do a bug shoot in my light arena until the refrigerator time had taken a toll on some of the specimens I collected, including this beetle, which was unable to stand upright. Hence the odd postures.

Tenebroides bimaculatus.
I just fond this beetle in Marshall's "Insects: Their Natural History and Diversity." I knew it had to have a name that noted its markings :-)

I think Don Chandler will want this one for the university's collection since it's not on the New Hampshire species checklist.

 
I do!
Thanks for bringing it to my attention.
