Notes on the foraging behaviour and taxonomy of the southeast Asian termite Longipeditermes longipes (Termitidae: Nasutitermitinae)

Abstract

The southeast Asian termite Longipeditermes longipes (Nasutitermitinae) forages above ground during the day in highly organised columns of workers protected by numerous soldiers. Preliminary data are presented on its foraging activity, based on observations of one colony in southern Kalimantan, Borneo. Foraging columns were observed on 7 of the 15 days, including successive days interspersed with periods of inactivity. Termites marched in columns to feeding sites along trails, reusing the same trails on successive days. Trail length varied from 7.0m to 14.5m. The termites were observed feeding on leaf litter and rotting tree trunks, and the workers displayed a division of labour between gnawing plant material and carrying the fragments back to the nest. Details are provided of soldiers and workers collected from tree canopies using insecticidal fogging. One of the two other species in the genus, L. mandibulatus, is shown to be a junior synonym of L. longipes.
