Camponotus fergusoni

McArthur (2003) - Minor workers observed leaving and returning to nest during the day. The heads of major workers were sometimes observed blocking a nest entrance in heavy soil (G. Weber pers. comm. 2003).

Identification
McArthur (2003) - Similar to Camponotus chalceus. Minor workers distinguished by a covering of very fine dense white pubescence covering the reticulate integument whereas in C. chalceus pubescence is sparse, integument finely punctate; both mostly black, mesosoma usually with some red; propodeal dorsum concave.
