Camponotus rufipes

De Oliveira et al. (2015), studying ant occupancy of Cecropia trees in southwest Bahia, Brazil, found two colonies of  opportunistically nesting in Cecropia pachystachya trees while Fagundes et al. (2010) found it nesting in bamboo.

Biology
Sanz-Veiga et al. (2017) - This species was observed visiting the extrafloral nectaries of Tocoyena formosa plants occurring in a southeastern Brazilian cerrado study-site.

Chemical Ecology
LeBrun et al. (2015) found a behaviour, first noted and resulting from interactions between Solenopsis invicta and Nylanderia fulva, that detoxifies fire ant venom is expressed widely across ants in the subfamily Formicinae. This behavior was also studied and shown in experiments with C. rufipes. See the biology section of the N. fulva page for a description of acidopore grooming and the use of formic acid for detoxification of a specific class of venoms that are produced by ants that may interact with formicines in the context of predation and food competition.
