Plant: Mitchell lists Aster, Chrysopsis, Haplopappus (Rayjacksonia or Croptilon), and Heterotheca; Flies August-October, North Carolina-Florida-Mississippi (coastal plain sp.)
County Records: Highlands (Norden et al. 1992); Miami-Dade (Graenicher 1927?)
Dates: Flies in October (Graenicher); Norden et al. (1992) found it in flight from late July-early November. Believed to be univoltine
Plant: collected on Chrysopsis tracyi only (Graenicher); Norden et al. (1992) found it on Heterotheca subaxillaris and Chrysopsis microcephala, collecting pollen from H. subaxillaris and nectar from both.
Notes: Originally thought to be endemic to SE coast of Florida (Miami-Dade to Palm Beach?); Recent collections from the central sand ridge area (Norden et al. 1992) have expanded its range to the south-central peninsula. Perhaps, it occurs in two disjunct areas (the sandy areas of southeastern Florida and the central sand ridge). Norden et al. (1992) also found much greater morphological variation in males than that of the original type specimens and males may not key out using the key in Mitchell. Females key out ok. Males show variation in head size and gena tubercules, with larger males having tubercules and smaller males lacking them.
