Natural History
In Costa Rica I have found workers foraging on the ground in the town squares of La Cruz and Liberia in Guanacaste Province, and from a treetrunk in a landscaped area in front of the Juan Santa Maria International Airport. I have collected workers while sweeping low vegetation along the dusty roadside near La Pita, on the road from the PanAmerican Highway to Monteverde. Phil Ward collected a queen at the beach margin in Corcovado National Park and he tentatively identified it as C. emeryi. On the Atlantic side of Costa Rica, I collected workers on the beach margin beneath coconut palms near Puerto Viejo de Limon. I have a queen from a Malaise trap at La Selva Biological Station that I am tentatively identifying as emeryi. Joel Dunn collected a nest from the domatium of a Cordia alliodora tree at La Selva.
Comments
I used to differentiate two species, emeryi and wroughtonii, based on relative scape length and shape of the clypeus. With additional collections these differences have blurred, so for now I am identifying all relevant material as emeryi.
