Explanation of Names
Phaedon desotonis Balsbaugh 1983
Described from a single male collected in 1963 in DeSoto State Park, AL(1)
Size
3-5 mm(2)
Identification
Similar to P. virdis; see dorsal habitus photos of both and diagnostic features(2)
Range
TX-FL-SC-OK (2)(Smith-Rodgers 2012)
GA, SC, TN (Wheeler & Hoebeke 2001)
AR(3)
FL(2)
TX (E.G. Riley, pers. comm. to MAQ)
OK (BG data 2008)
Food
Hosts: Coreopsis spp. and Bidens aristosa (Asteraceae) (Braman et al. 2002, Smith-Rodgers 2012, Thomas 2004)(2); common on Greenthread (Thelesperma filifolium, Asteraceae) in TX & AR (Smith-Rodgers 2012)(4)
Life Cycle
Adults overwinter (Wheeler & Hoebeke 2001)
Remarks
Apparently a case where a relatively rare plant-feeding insect species has 'jumped' from its rare native host to related common hosts and is now expanding its geographical range. (Smith-Rodgers 2012)
There is some evidence that this beetle may be some foreign species recently adventive to North America. (S.M. Clark, pers.comm. to =v=, 29.v.2014)
