Explanation of Names
Disonycha arizonae Casey 1884
Type Locality: Cochise, Arizona
Numbers
36 spp. n. of Mex (1)
Identification
Note the small dark flecks on the pronotum and the coarse elytral punctation. (E.G. Riley, pers. comm)

Det. E. G. Riley, 2013
Range
e. NA to AZ (AZ-FL-ON-MB) / Mex (2)
Food
Reported from various unrelated plant families (3)
Remarks
Disonycha species can eventually be found on their breeding host, but for arizonae, I have never found it in series or with larvae, despite the fact that it is a wide-ranging species. Most collecting events for the species generate one specimen at a time – like yours. (E.G. Riley, pers. comm., 2013 to MAQ)
