Texas County Records for Zopherus nodulosus haldemani

(Plus Bee, Bosque, Burleson, Burnet, Dallas, Ellis, Hood, Menard, Kendall, Kimble, Parker, Palo Pinto & Tarrant Counties)

Primary County Record Source: E.G. Riley, Dec. 2005

Range: East-Central Texas. 

Adult Activity: Starts as early as March 8 in Austin (pers. observ.) and continues as late as October.


Adults, larvae, and pupae were once found on a Pecan tree (Taber & Fleenor, 2003). Adults have also been collected on dead Oak trees. Taber & Fleenor (2005) saw several mating pairs on an American Elm. The females appeared to be laying eggs in the bark's crevices.

Similar Species:  

Triplehorn (1972) recognized a total of 19 species on Zopherus, all from the Americas, ranging from Venezuela north to the southwestern United States. Ten species occur across the southwestern United States, though none resemble Z. nodulosus.

Texas Taxa:

Zopherus concolor LeConte 
Zopherus nodulosus haldemani
Zopherus xestus

Horace Haldeman was one of the first persons to concentrate on collecting insects in Texas. He sent his specimens, mostly beetles, to his entomologist brother, Samuel S. Haldeman, and a noted coleopterist, John L. LeConte, for description.
