Natural History

Discothyrea are extremely small, cryptobiotic inhabitatants of forest leaf litter (see Genus Overview).

This species inhabits wet forest habitat in the Atlantic lowlands. It is a rare species known from few collections. Two workers have been collected: one from a Project ALAS Winkler sample from the 300m site (Cantarrana) on the Barva transect in Braulio Carrillo National Park, the other from a Project TEAM Winkler sample from La Selva Biological Station. Two alate queens have been collected, each from a separate Project ALAS canopy fogging sample. Canopy fogging samples are taken at dawn.
