The Catasetinae is a subtribe within the Orchidaceae. Its members are widespread in lowland tropical Central and South America up to 1,500 meters. They are found on trees, stumps or old fence posts.
Catasetinae are exclusively pollinated by male euglossine bees, which are attracted to the floral fragrances, and collect them. A particular Catasetinae species may attract only one or a few species of bees from the dozens that occur in the habitat.[1]
Three related genera – Cyrtopodium, Galeandra and Grobya – are sometimes separated as subtribe Cyrtopodiinae, sometimes included in the Catasetinae.
