Oligophagy

 

the habit in some animals of eating only certain kinds of food. Oligophagous animals are contrasted to monophagous ones, which consume only one kind of food, and to polyphages, which consume many kinds of food. Oligophagy is characteristic of arthropods, including insects, spiders, ticks, mites, and crustaceans. Oligophagous worms, mollusks, fish, and birds can be insectivorous, granivorous, carnivorous, piscivorous, or bird-eating; oligophagous mammals can be herbivorous, frugivorous, or nectarivorous. Oligophagous animals are widely distributed in tropical forests but are comparatively rare in temperate and high latitudes.

Among the 8 ciid species without an attributed feeding habit, 3 showed a tendency to oligophagy: Cis sp.3 (comptus group) and Cis diadematus Mellie, each with 3 occurrences only in Polyporaceae species; and Cis kawanabei Lopes-Andrade, with 4 occurrences in Rigidoporus spp.
The specialization in closely related hosts (oligophagy), rather than in a single host species, would be the most advantageous strategy, because these hosts would be more efficiently located, and variations in population dynamics of a single fungus species would not affect the availability of resources to such ciid species.
