( Fig. 67 A–J View Figure 67 ). Similar in coloration and shape to female. As well as female, male has the first five proximal antennal flagellomeres with two colorations: dorsally lighter (yellow) than ventrally (brown), remaining flagellomeres brown on both sides.
David (Dave) R. Smith is interested in the systematics and biology of world sawflies ( Hymenoptera : Symphyta) and parasitoid wasps ( Hymenoptera : Evanioidea, Trigonalyidae ). Currently, he is an emeritus research entomologist at the United States Department of Agriculture Department of Agriculture ( USDA), the Systematic Entomology Laboratory ( SEL), Washington, D.C., USA .
Parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao ( Estación Cacao and Sendero derrumbe ) and Sector Pitilla (Sendero Evangelista and Sendero Orosilito) during May 2001, July 2002, December 2003, and August 2011 at 660 m, 900 m, 1,150 m, and 1,220 m in rain and cloud forests.
The lifestyle of this parasitoid species is gregarious.
Antiblemma leucocyma Hampson ( Erebidae : Eulepidotinae) feeding on Conostegia xalapensis , Miconia brenesii , and Ossaea brenesiior ( Melastomataceae ) and Antiblemma sp. Hübner feeding on Henriettea tuberculosa ( Melastomataceae ). Caterpillars were collected in fourth and fifth instar.
