Chlaenius tricolor - male

Chlaenius tricolor - Male
Vicksburg, Warren County, Mississippi, USA
May 11, 2010
Size: 12.55mm
Collected at light trap. When the light strikes these beautiful creatures, the head is metallic green, the pronotum metallic purple and the elytra a deep rich blue. A data submission for MS/May.


no match to emarginatus [mandibles, pronotum]

I keyed this out using "Ground Beetles and Wrinkled Bark Beetles of
SC" to C. tricolor tricolor, although I do not know how that may
translate range wise to the beetles of Mississippi.

Chlaenius tricolor
does indeed fit the image and the location. Pretty.

Thank you Peter. Question, where can one get checklists of beetles
found in a state. Florida has an excellent source, both in print and
on the web. What other states have a similar product that you know
of. I just finished a 22 state road trip and would have loved to
have had a better idea of what was in each area. Tks VR Bruce

Best single reference for geographic distributions
for all of North American Carabidae is:

Bousquet, Y., and A. Larochelle. 1993. Catalogue of the Geadephaga (Coleoptera: Trachypachidae, Rhysodidae, Carabidae, including Cicindelini) of America North of Mexico. Mem. Entomol. Soc. Can. 167: 1-397. Out of print but available in university or entomolgy department libraries. Each species name is followed by a list of known occurrences in states and provinces. Be aware that a long-awaited revision is forthcoming next year likely.

Conversely, I am aware of several published carabid checklists for certain states and provinces -- too many to mention in a short reply. My only interest is in Carabidae so I don't keep track of checklists that ignore that group.
