Camponotus senex is a fairly common species of weaver ant from the New World.

They are opportunistic cavity-dwellers, semi-nomadic carpenter ants which are found around grasslands in Central and South America.

[3] C. senex are medium-sized and agile, and can be frequently found inside the abandoned outer crusts of termite nests.

[2] Very little is known about their biology as C. senex remains a poorly studied species, in spite of being so common.

They contain anchor-tipped dorsal hairs when mature, which may signals for a morphological adaptation to be hung inside the ant nest.
