Biology

Foraging/Diet

Camponotus saxatilis collect honeydew. Novgorodova (2015b) investigated ant-aphid interactions of a dozen honeydew collecting ant species in Western Siberia pine and aspen-birch-pine forests (54°7´N, 83°06´E, 200 m, Novosibirsk) and mixed-grass-cereal steppes with aspen-birch groves (53°44´N, 78°02´E, 110 m, near Karasuk) in the Novosibirsk Region and coniferous forests in the northeastern Altai (north end of Lake Teletskoe, 51°48´N, 87°17´E, 434 m). All of the ants studied had workers that showed high fidelity to attending particular aphid colonies, i.e, individual foragers that collect honeydew tend to return to the same location, and group of aphids, every time they leave the nest. Camponotus saxatilis also exhibited other forager specialization. Some workers specialized on attending specific aphid colonies. These foragers did collect honeydew but a majority of their time was spent guarding the aphids. Another subset of the foragers showed a tendency to specialize on transporting honeydew as they were more active in soliciting from foragers attending the aphids than typical unspecialized foragers. This in turn allowed those ants attending aphids to remain at the aphid colony and thereby protect it for long periods of time. Camponotus saxatilis tended Symydobius oblongus (Heyden) and Aphis craccivora Koch.
