Biology:

There is some question as to whether the Florida population of C. varians is native (e.g. Deyrup et al., 1988; Deyrup et al., 2000)or introduced (e.g. Wittenborn & Jeschke, 2011). The species is otherwise known only from the Bahamas and Cuba (De Andrade & Baroni Urbani, 1999). Deyrup et al. (2000)refrained from classifying C. varians as introduced to Florida, arguing that the species may have been transported in floating trees, and dislodged mangroves in particular. Non-native Cephalotes species, including the widespread C. pusillus (Klug), are occasionally intercepted at US ports of entry.
