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)
