James Robertson is a coleopterologist interested in biodiversity, evolution, and ecology of Cucujoidea [ Erotylidae (pleasing fungus beetles), Bothrideridae (ectoparasitic, cocoon-forming beetles), Cerylonidae (minute fungus beetles), Corylophidae (minute hooded beetles), and Discolomatidae (Mexican hat beetles)]. He is a postdoctoral associate at the University of Arizona, Tucson, AZ, USA.
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Pitilla (Sendero Laguna), Sector Rincón Rain Forest ( Río Francia Arriba, Sendero Albergue Crater, and Sendero Rincón), and Sector San Cristóbal (Bosque Trampa Malaise, Sendero Perdido, Quebrada Cementerio, and Quebrada San Francisco), during January and March 2004, June, October, and December 2005, December 2006, October 2007, and November 2010 at 400 m, 430 m, 620 m, 690 m, and 700 m in rain forest.
Adult parasitoids were collected in Costa Rica, ACG, Sector San Cristóbal (Bosque Trampa Malaise and Potrero Argentina), during August 2007 at 520 m and 815 m in pasture and rain forest.
The lifestyle of this parasitoid species is gregarious.
Antiblemma sp. Hübner ( Erebidae : Eulepidotinae) feeding on Psychotria chagrensis , P. graciliflora , and Psychotria panamensis ( Rubiaceae). Caterpillars were collected in third, fourth and fifth instar.
