Cylindrical Bark Beetle - Bitoma quadricollis

Cylindrical Bark Beetle - Bitoma quadricollis

June 1, 2008
Size: ~3.3mm
I believe this is a Cylindrical Bark Beetle. But I've never found one before, so corrections / conformations welcome :) came to UV light.

In this season of thankfulness, I’m grateful for many things including BugGuide. The wonderful bugs with endless variety and detail are the stars. But I’m especially thankful for the people of BugGuide who contribute, edit, and ceaselessly maintain this wonderful site. Thanks BugGuide!

can't wrap my mind around it... ??pinicola
time permitting, could you add a clear antennal shot?

 
maybe . . .
I assume you saw them on the ventral image. Is there a particular part or aspect of the antenna you'd like to see? At 3.3mm I may be at the limits of my setup, but I'll give it a go with my highest magnification.

 
i kinda wanted them against a light background...
never mind, Tim-- i just try to conceal my ignorance by being finicky

 
You are a riot, Belov!
You're our beetle guru :-)

 
my vote
=V= mentioned this one to me. I'd say Bitoma quadricollis. The eyes are too close together underneath to say pinicola. They are a little wider apart than Stephan suggests but I have quadricollis from TX and LA with this separation. The margins of the pronotum look correctly toothy.

 
thanks, Rick
what does Stephan say about quadricollis's range? Any NJ records? D&A book doesn't list NJ, but says the beast goes as far north as MA.

 
NJ
Stephan hand-wrote several extra states for quadricollis in the copy he gave me, but NJ is one of the states he already had listed in the publication.

 
great -- thanks again
