Natural History

One collection of this species was from Sirena in Corcovado National Park. This is a lowland rainforest site. At 0600hrs, a column was crossing a trail and entering a hole in the ground. The end of the column disappeared down the hole as I watched. A second collection was workers obtained in a Malaise trap sample at the 500m site (El Ceibo) on the Barva transect in Braulio Carrillo National Park. The type specimens were collected near San Josˇ in the early 1900's.
