The dietary spectrum of the namib desert dune antCamponotus detritus

  • B. A. Curtis
Article

Summary

The major food ofCamponotus detritus throughout the year was found to be honeydew excreted by aphids and scale insects present on the perennial vegetation in the dune habitat. This was supplemented by pollen, nectar, dead animal material and possibly bird and lizard faeces. Moisture was obtained from honeydew as well as directly from condensed fog water and occasional rain. The gasters of workers were capable of considerable distention, allowing them to take up from 48–84% of their body weight in liquid. Workers generally foraged individually, although recruitment to new food sources was sometimes observed. No food stores were found.

Comportement fourrageur et nutrition de la fourmi Camponotus detritus dans le désert de Namibie

Resume

La nourriture principale deC. detritus au cours de l'année consiste en exsudats sucrés d'Homoptères présents sur la végétation pérenne des dunes. Cette nourriture est complétée par du pollen, du nectar, des débris d'animaux morts et, peut-être, des fèces d'oiseaux et de lézards. L'eau nécessaire à la vie des fourmis est obtenue à partir du miellat, de l'eau de condensation des brouillards et, de temps à autres, des pluies. Les gastres des ouvrières sont capables d'une grande tension leur permettant d'absorber de 48 à 84% de leur poids en liquide. Le plus souvent les ouvrières récoltent individuellement, une certaine collaboration dans la collecte de nouvelles ressources alimentaires ayant parfois été observée. On n'a jamais localisé de réserves dans les nids.
