Weevil on Mexican Blue Oak flowers - Tachygonus lecontei

Weevil on Mexican Blue Oak flowers - Tachygonus lecontei
Florida Canyon, Pima County, Arizona, USA
April 22, 2012

Moved from Tachygonus rhombus.

Henry Hespenheide says:
"This is a specimen of T. lecontei, NOT T. rhombus. It is NOT a new state record, as I cite specimens of lecontei that I collected in the Chiricahuas in my revision of the genus for America north of Mexico:
Hespenheide, H.A. 1992. A review of the genus Tachygonus Schoenherr (Coleoptera: Curculionidae) in America north of Mexico. Proceedings of the Entomological Society of Washington 94: 1-11.

If you want a copy of the paper let me know. T. lecontei is associated with oaks, T. rhombus with herbaceous legumes as far as I know (I haven't collected it), so the association of this specimen with oaks is consistent with its known ecology."


Tachygonus rhombus Casey Probably a teneral individual. collected in numbers from AZ in Casey 1897 and Champion 1906 but only 3 recent records from Tucson and Sabino Canyon, Catalina Mts.and Mexico south to Panama. See Hespenheide 1992, Proc. Wash. Ent Soc.94(1:1-11.

Moved from ID Request.

Note: there is
only T. centralis and rhombus in O'Brien's book for AZ. I have centralis, too. This really looks like lecontei. New State record?

Finally from different state!!

Not a lecontei after all... Come on eastern people! Find it! lol

This is better, though!
