Biology:

In Fiji: Camponotus chloroticus is a Melanesian member of the C. maculatus group. The C. maculatus group includes a wide diversity of poorly studied forms from the Old World that have been variously referred to as species, subspecies, varieties and races (McArthur & Leys, 2006). It is uncertain which species Mann (1921) refers to, as he listed his original Fiji material as belonging to an unnamed variety of C. maculatus subsp. pallidus F. Smith. Although Mann described the specimens as being, "exceedingly close to, if not identical with var. samoaensis Santschi," he did not formally list them under that name. Wilson and Taylor (1967: 93) placed Santschi's material (samoaensis is an unavailable name because of its infrasubspecific status) under C. chloroticus Emery. Suffice it to say, whatever the true identity of this species, it is widespread across the Pacific and is in need of significant revision. Without a thorough review of the maculatus group across the Pacific, it is difficult to say whether pallidus, chloroticus or another of the myriad available names most appropriately applies to Fijian material.

There is some variation of this species across the archipelago with respect to size and color, but none of the specimens examined match the descriptions of its presumably close Pacific relatives, the darker headed C. navigator Wilson & Taylor or C. variegatus Fr. Smith with its more banded gaster. The species was collected most frequently in the smaller islands and the coastal sections of the larger islands. Colonies were found nesting in dead branches, in live mangroves, and under tree bark.
