SUBFAMILY MICROGASTERINAE i^e 



The subfamily Microgasterinae is the richest in species of all the subfamilies in the 

 Braconidae. The genus Apanteles is a particularly large group, containing nearly 

 two hundred known North American forms. All the species, so far as known, are 

 endoparasites of lepidopterous larvae, some being gregarious parasites, others solitary; 

 and many of them rank among our most valuable natural enemies of injurious insect 

 species.
