which species? - Xylotrechus aceris

which species? - Xylotrechus aceris
Nashua, Hillsborough County, New Hampshire, USA
July 26, 2006
Size: about 13.5 mm
This handsome Xylothechus came to my MV light on a hot, humid night. I would say it looks most like the image of X. int*eger in Yanega's book, but the markings are stronger and simpler on mine.

Moved from Xylotrechus.

I've changed my mind.
I now think X. aceris, the Gall-making Maple Borer, is a better match with its narrower, less sloping shoulders and specific shape of markings.

Take a look at X. aceris. Th
Take a look at X. aceris. They've got the four white pronotal markings. X. integer seems to have alot more pronotal markings than this guy.

 
Thanks for the suggestion, Crystal.
I switch back-and-forth, back-and-forth till my eyes go crossed and I still see nothing that's conclusive for me :-( Maybe there's a feature someone can point to that cinches it for me.

 
V or Oval?
Downie and Arnett diverge these two Xylotrechus with the first key couplet. "Frontal carina V or Y shaped" leads to X. integer, "Fronal carinaton oval, closed at each end; in some elongate" leads to X. aceris

hope this helps,
Tim

 
Drat it.
Okay, from now on I'll hold any Xylotrechus I get in position to capture a face shot of the frontal carina. I've already released the carina and attached beetle to the great outdoors. Thanks for the pointer, Tim.
