a load of Corticeus - Corticeus

a load of Corticeus - Corticeus
Nashua, Hillsborough County, New Hampshire, USA
March 27, 2008
Size: 3.5 - 4 mm
I felled a pine tree that had died in the front yard Wednesday (the same day I cut down a red oak tree mentioned in another post) and today I spent some time stripping bark from the log lengths. I found lots of bark borers (Scolyt*inae) and longhorn larvae (Cera*mbycidae) plus 15 Corticeus, 11 of which are pictured here. I was happy to find these because I had promised some to Don Chandler a couple years ago. Perhaps he will be able to key them to species.

I had cut the tree no more than two inches off the ground and found all the Corticeus in the first foot or so of trunk. I'm inclined to dig around the stump and see if these beetles are under the bark that was underground.

corners?
When I have a look on the group image, to me the one in the lower RIGHT corner looks different (smaller, shorter body, colour lighter).

 
I agree, it does look different.
All I know is Don had approx. 10 beetles that probably represented both collection sites and was able to examine them under the scope. He may or may not have had either of the individuals considered here. I suppose I should inventory my captive specimens to see if *I* have the one in the lower right corner.

Moved from Corticeus.

Corticeus praetermissus
is the one in the lower left corner. Of the material sent, there were about 10 C. parallelus, and one of this species.

 
I did something rather stupid.
I mixed batches of Corticeus from sites a mile apart even though I knew that we had more than one species in the area. Therefore, your discovery of two species among those I sent could indicate a different species populating each site. I guess we'll never know :-(

 
Still
"Nashua", though it would be nice to know if they do occur together or have distinct and separate niches.

I found 6 - 8 more today.
They were maybe a mile away under bark of two large dead pines, both of which contained a few Rha*gium inqui*sitor adults and larvae, one of which had quite a few Pyt*ho Pla*nus adults and larvae, and the other of which contained the tiniest scoly*tids I've ever seen.

Great stuff.
Keep them coming!
