Nabbed this big, frisky carabid on the wall of the observation deck of the Mt. Washington Meteorological Observatory during an unusually calm and balmy day atop the peak known for the "world's worst weather." This looks like Calosoma frigidum to me but I'd like a second or third opinion.

A twenty-year veteran staffer in the observatory building says there are usually four or five days a year there with similar weather conditions when many insects swarm to the summit looking for sex partners. Last year, however, there were a great many calm days and this
hilltop lekking was a regular occurence.

I think this beetle was the only carabid I saw in an hour or so of serendipitous collecting there. Although carabids are generaly hardy, this beetle did not fare well in the fridge and was not able to give me an alert pose in the light arena. Here the beetle has died and been posed in silica gel crystals to rapid-dry it in more-or-less the position I wanted.

Finding this and a great many other species was a collateral benefit from our search for Pytho strictus, the lost beetle of Mt. Washington.
