Henry Keith Townes Jr. (20 January 1913 - 2 May 1990) was widely known for his work on hymenopteran systematics, particularly the large and difficult family Ichneumonidae .
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao (Sendero Nayo and Sendero Toma Agua), Sector Del Oro ( Metereológico), Sector Mundo Nuevo (Sendero Melón), and Sector Pitilla (Sendero Evangelista), during February and August 1998, September 2002;, April 2003, June 2007, and January and October 2010 at 361 m, 590 m, 660 m, 1,090 m, and 1,140 m in intergrade dry-rain, rain and cloud forests. The adult parasitoid was collected in Costa Rica, ACG, Sector San Cristóbal (Bosque Trampa Malaise), during July 2007 at 815 m in rain forest.
The lifestyle of this parasitoid species is gregarious.
Heterochroma sarepta (Druce) ( Noctuidae : Amphipyrinae ) ( Fig. 4SView Figure 4) feeding on Smilax mollis and S. spinosa ( Smilacaceae ). Caterpillars were collected in second, third, fourth and fifth instar.
