Sotol stalk pupa -- REALLY dark now - Thrincopyge alacris

Sotol stalk pupa -- REALLY dark now - Thrincopyge alacris
Organ Mts., Las Cruces, Dona Ana County, New Mexico, USA
March 28, 2006
Size: 18 mm approx.
If that pronotal pattern closely matches the adult pattern, I wouldn't be surprised if this buprestid could be IDed at this stage, before it expupates.

Thanks Phillip and Joshua.
Thanks also to Rick Westcott, who emailed me that it was Thrincopyge alacris LeConte. I should have another one-to-several gnaw their way out of the sotol stalk section I brought back to New Hampshire from my Dec. 24 - 31 trip to Las Cruces NM. This one is keeping us in suspense :-)

Just for fun, I've moved this to species page. I can move it again if needed after it expupates.

only thing I can think of is ..
Thrincopyge sp., maybe ambiens or alacris (only 2 spp.). A couple of Acmaeodera spp. are recorded from Dasylirion wheeleri, but those just don't look right to me. Shouldn't be long now and we'll know for sure.

Phillip, I have 6 or so of the T. alacris and among those specimens I think there is 3 variations. So, I agree also that this species varies alot.

I agree, I think it is Thrincopyge spp. I think it is Thrincopyge alacris instead of T. ambiens.

 
Wrong link
I fouled up, the link above to T. ambiens actually shows alacris
