1899 C. Robertson in Bot. Gaz. 28 29 The difference between a monotropic and an oligotropic bee may depend merely upon the accident that only one species occurs in the neighbourhood.
1946 C. T. Brues Insect Dietary iii. 107 Some more specialized bees and other insects restrict their visits to a much more circumscribed assortment of plant species. With these oligotropic kinds the advantages to the plant are obviously greater.
1994 Proc. National Acad. Sci. U.S.A. 91 3 The monotropy type occurs in plants pollinated by hymenopterans with species-specific or group-specific flower preferences for nutritive purposes (monotropic and oligotropic bees and fig wasps).
