Cotesia urabae Austin & Allen is a solitary larval endoparasitoid which is part of a large complex of 11 primary parasitoids of Uraba lugens Walker, many of which are polyphagous (Allen, 1990a, 1990b). Adult C. urabae have a black body with yellow–brown legs, and they are 2.5-3.2 mm long (Austin and Allen, 1989). The female oviposits its eggs inside a U. lugens by inserting its ovipositor into the larva, and it has been found that one female may carry up to 400 eggs (Allen, 1989). It has been observed that C. urabae females are able to attack the same larva several times; despite this only one single parasitoid completes its development in each larva (Berndt, 2010).
