( Fig. 36 A–L View Figure 36 ). The body coloration is lighter in males than in females.
Robert (Bob) A. Wharton is an American entomologist whose research is focused upon the evolution of behavior and life histories in parasitoids, especially Opiinae and Alysiinae ( Braconidae ). He is an emeritus professor at the Department of Entomology, Texas A&M University, College Station, TX, USA.
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Pitilla (Sendero Mismo), Sector Rincón Rain Forest (Sendero Rincón), and Sector San Cristóbal (Sendero Perdido), during February 2003, October 2004, and February 2005 at 430 m, 620 m, and 680 m in rain forests.
The lifestyle of this parasitoid species is solitary/gregarious.
Ochrodota marina Schaus ( Erebidae : Arctiinae) feeding on Ocotea leucoxylon ( Lauraceae ); Symphlebia tessellata (Schaus) ( Erebidae : Arctiinae) feeding on Pouteria viridis ( Sapotaceae ); Periga cluacina Druce ( Saturniidae : Hemileucinae) feeding on Carapa guianensis ( Meliaceae ). Caterpillars were collected in second and third instar.
