Neocorynura tica is a small (about 7 mm long) dark green bee with metallic greenish-yellow highlights. Brosi et al. (2006) describe the species, including photographs and illustrations of the bee and its nest. Nest architecture: the nest was a burrow dug into a ded, wet, rotten stick densly covered with moss and lichens about 1.6m above the ground. The nest included five sealed cells, and two open cells being provisioned with pollen. Each sealed cell contained a male pupa. The cells were not oriented in a common direction, as is common with wood-nesting species, where the shape and softness of the wood often determine tunnel and cell placement and orientation. The nests were very similar to those of the stick nesting sweat bees of the genus Megalopta. The cell walls were built with fine sawdust, with the inner surface lined witha waterproof secretion. There were two adult females and two adult males in the nest; more may have been away foraging when the nest was collected. Parasites: the authors note that the nest they collected contained a mutillid wasp larva and individuals of Megaselia sp. phorid fly. The specimens for this study were caught as part of an intensive trapping regime in forest fragments and surrounding countryside in the Costa Rican cloud forest. Because no individuals were caught outside of the fragments, despite the intensive trapping, it is likely that this species requires a forest habitat. Although there were two females in the nest at the time of collection, it is likely that one was a recently emerged adult who had not yet dispersed. Without more intensive observatons of more nests it is impossible to say, but this species is apparently solitary.
