small, black, elongate, under pine bark weevils - Cossonus corticola

small, black, elongate, under pine bark weevils - Cossonus corticola
Nashua, Hillsborough County, New Hampshire, USA
March 11, 2007
Size: about 4.75 mm
I've encountered small, black, shiny weevils under pine bark before but I'm not sure I've ever seen any alive. These were no exception. In fact, there were more pieces than whole specimens.

Cossoninae
These are in the subfamily Cossoninae, but I don't know the genus offhand.

 
Cossoninae
Thanks, Brad.

 
Cossonus
I'm pretty sure now the genus is Cossonus. If you still have the specimens and can get a frontal shot, I can probably tell species. Although I suspect it is Cossonus corticola.

 
Okay, Brad.
The frontal views have been added for you.

Beetle fragments
While hiking a few days ago, I peeled back some hardwood bark to find a multitude of Bark Beetles. They were all tucked neatly into their burrows, and many were still covered in wood shavings. It was as though the insects had been frozen in time while they were still tunnelling! I gently prodded a few of them, only to shatter their exoskeletons into countless fragments. None of the beetles were alive. I wonder what causes such mass 'graveyards'. Those are some cool weevils, by the way.

 
Thanks, Stephen.
When you think about it, where *should* a beetle die? Borers are special I guess because the adults do tunnel before laying eggs. I guess that's their final task in life, then they die in their tracks.
