The parasitized caterpillars were collected in Costa Rica, ACG, Sector Rincón Rain Forest (Conguera, Quebrada Escondida), Sector Pitilla (Coneja, Sendero Naciente), and Sector San Cristóbal (Potrero Argentina), during November 2009; January and October-November 2010; and April 2011 at 415, 420 and 700 m in rain forest.
Adult parasitoids were collected in Costa Rica, ACG, Sector El Hacha (Sendero Bejuquilla), Sector Rincón Rain Forest (Vado Río Francia), and Sector San Cristóbal (Bosque trampa Malaise, Río Blanco Abajo, and Potrero Argentina), during November 1998, July-August and October-December 2007, and March 2008 at 280 m, 400 m, 500 m, 520 m, and 815 m in pasture, intergrade dry-rain, and rain forests.
The lifestyle of this parasitoid species is solitary.
