Natural History:

Camponotus chartifex inhabits mature lowland rainforest. Workers are most often encountered as isolated foragers, day or night. Like Camponotus in general, they appear to be generalized scavengers with a predilection for sweets.

This species and its relative, C. nitidior, build nests of sewn-together leaves (Wilson 1981, Fern‡ndez 2002). They use larval silk to attach leaves together and to make silk sheets and baffles. The nest walls are a combination of leaves and silk sheets. The silk sheets and baffles are a combination of silk and masticated plant fibers.

I have only found one nest of chartifex. At Tortuguero I found a nest between two leaves. The leaves were sewn flat together, with the nest sandwiched between them. The nest was roughly circular, about 4cm diameter.

Notes:

The subgenus Dendromyrmex has been revised by Fern‡ndez (2002).

[[ worker ]] Laenge: 7 mm- Rothbraun, ziemlich glaenzend, der Hinterkopf und eine Makel auf der Scheibe des Pronotum, und die Tarsen, mit Ausnahme der zwei letzten gelben Tarsenglieder schwaerzlich. Die abstehende Behaarung ist gelbweiss, ziemlich reichlich am ganzen Koerper. In der Form der Koerpertheile findet eine vollkommene Uebereinstimmung mit der vorigen Art statt, und es finden sich nur Unterschiede in der Farbe und Skulptur. Die Mandibeln sind stark glaenzend, mit wenigen groben Puncten, sonst glatt. Der Clypeus und die Wangen sind netzmaschig, am Hinterkopfe sind die Maschen kleiner und tiefer, und die Skulptur wird gegen den Hinterrand des Kopfes fingerhutartig punctirt, theilweise aber auch querrunzlig. Der Thorax ist auf der Scheibe sehr fein quer lederartig gerunzelt, am Mesonotum und Metanotum stark aber fein quergerunzelt. Der Hinterleib ist sehr fein lederartig quergerunzelt.

Vom Amazonenstrome (Mus. Caes).
