Robert (Bob) Kula is a research entomologist with the Systematic Entomology Laboratory, Agricultural Research Service, United States Department of Agriculture ( USDA), Washington, DC. He is an adjunct scientist with the Smithsonian Institution and is curator of Ichneumonoidea at the National Museum of Natural History, Washington, DC. His research focuses on classification, evolution, and biodiversity of parasitoid wasps in Braconidae .
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao ( Estación Cacao, Sendero a Maritza, and Sendero Ponderosa), Sector San Cristobal (Sendero Pinyal), and Sector Pitilla (Sendero Mismo), during July 2003, August 2006, October 2008, May 2009, and January and July 2010 at 570 m, 630 m, 680 m, 1,060 m, and 1,150 m in rain and cloud forests.
The lifestyle of this parasitoid species is solitary/gregarious.
Eois sp. Hübner ( Geometridae : Larentiinae) feeding on Piper augustum , P. glabrescens ( Piperaceae ); Hagnagora mortipax Butler ( Geometridae : Larentiinae) feeding on Clethra mexicana ( Clethraceae ); Semaeopus illimitata Warren ( Geometridae : Sterrhinae) feeding on Abuta panamensis ( Menispermaceae ); undetermined species of Geometridae feeding on Trema micrantha ( Cannabaceae ). Caterpillars were collected in first, third, and fourth instar.
