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.[1][2] It is taxonomically believed to be a complex of cryptic species and was previously considered synonymous with Camponotus textor.which once included a distantly-related species of weaver-ant.[3]
Ecology
C. senex are medium-sized and agile, and can be frequently found inside the abandoned outer crusts of termite nests. They can inflict a respectable bite when handled carelessly. They're, however, not aggressive, and their nests tend to be sparse and mainly composed of satellite, queenless temporary nests under stones or bark.[2] Very little is known about their biology as C. senex remains a poorly studied species, in spite of being so common.[3]
The development of C. senex undergoes four larval instars. The larvae are typical Camponotus larvae: plump and hairy larvae that will spin a cocoon. They contain anchor-tipped dorsal hairs when mature, which may signals for a morphological adaptation to be hung inside the ant nest. They are the only ants apart from fire ants to present solenopsinalkaloids in their venom.[3]
