In the wild, adult female (Boling and Pitre, 1970)will usually deposit one egg in each noctuid moth larval host. Within two days the egg hatches into the first larval instar. The larvae then molt twice inside the host before emerging, killing the host, and immediately spinning a cocoon of roughly 4 mm in length on whichever surface it lands. At roughly 13 days from the implantation of the egg, the adult emerges from the cocoon fully developed. Although reproductively active immediately, the average adult has roughly 1 week to reproduce before death.
In order to reproduce, males locate the females by following pheromone trails. Once a female is located, a male fans its wings to signal to the female that he is ready to mate. If the female does not jump away or click it's wings, then the male mounts the female. Most likely due to the disparity in the male/female ratio of (Boling and Pitre, 1970), the male will attempt to mate multiple times, while the female mates once and rejects further attempts to mate. Currently, there are no known traits that influence mate preference.
As with most other parasitoid wasps, (Riddick, 2008)displays no parental investment.
Specific home range sizes forare currently unknown.
Adult black cutworms, celery loopers, common loopers, bean leaf-skeletonizers, corn earworms, tobacco budworms, spotted beet webworms, Hawaiian beet webworms, Leucania latiuscula, variegated cutworms, Plathypena scabra, armyworms, soybean loopers, Scotorythra caryopsis, cabbage loopers and several species of Spodoptera, including southern armyworms, beet armyworms, fall armyworms, Spodoptera ornithogalli, and Spodoptera praefica. (Boling and Pitre, 1970; Johanowicz and Mitchell, 2000)require a sugar source and are known to feed from the nectar of flowers as well as from the honeydew excretions of aphids. Female lay eggs within an insect host, which will serve as nourishment for the developing larvae. As a generalist parasitoid, larvae feed on the internal structures from a variety of insect larvae. Some of the species that are host to larvae include:
There are no known specific predators of (Raw, 1997). However, numerous birds as well as amphibians and other insects are known to opportunistically feed upon wasps.
The most notable role of Noctuidae family. Additionally, are known to directly affect the populations of other parasitic wasps such as Microplitis croceipes and Cardiochiles nigriceps by interspecific competition between the larval phases of the parasites. When multiple wasp eggs are present within the same host, the egg that is laid first is usually the only one to successfully hatch and mature into an adult. Commonly parasitized species include: black cutworms (Agrotis ipsilon), celery loopers (Anagrapha falcifera), common loopers (Autographa precationis), bean leaf-skeletonizers (Autoplusia egena), corn earworms (Helicoverpa zea), tobacco budworms (Heliothis virescens), spotted beet webworms (Hymenia perspectalis), Hawaiian beet webworms (Hymenia recurvalis), Leucania latiuscula, variegated cutworms (Peridroma saucia), Plathypena scabra, armyworms (Pseudaletia unipuncta), soybean loopers (Pseudoplusia includens), Scotorythra caryopsis, southern armyworms (Spodoptera eridania), beet armyworms (Spodoptera exigua), fall armyworms (Spodoptera frugiperda), Spodoptera ornithogalli, Spodoptera praefica, and cabbage loopers (Trichoplusia ni). (Boling and Pitre, 1970; De Moraes and Mescher, 2005; Johanowicz and Mitchell, 2000)is the population control it provides for the numerous species it parasitizes. These parasitic wasps mostly parasitize moths of the
Because of the nature of Noctuidae. Specifically, has been shown to be most effective at controlling herbivore populations feeding on maize due to an attraction to a certain blend of volatile chemicals produced from larvae feeding on the corn. (D'Alessandro, et al., 2009; Lai, 1988)as a noctuid larval parasitoid, it has proven to be a great asset to thousands of farmers growing a wide variety of crops damaged by species of
To date, there are no known economic issues caused by the presence of these parasitoid wasps. (Lai, 1988)
Currently, they are no apparent risks to this species. It is also unlikely that the (D'Alessandro, et al., 2009)population will be at risk in the near future, due to interest in them as a biological control agent.
Cotesia marginiventris is also known by the name of Apanteles marginiventris (Tingle, et al., 2005)

having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature.
the state that some animals enter during winter in which normal physiological processes are significantly reduced, thus lowering the animal's energy requirements. The act or condition of passing winter in a torpid or resting state, typically involving the abandonment of homoiothermy in mammals.

An animal that eats mainly insects or spiders.
fertilization takes place within the female's body
referring to animal species that have been transported to and established populations in regions outside of their natural range, usually through human action.
A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.
having the capacity to move from one place to another.
the area in which the animal is naturally found, the region in which it is endemic.
islands that are not part of continental shelf areas, they are not, and have never been, connected to a continental land mass, most typically these are volcanic islands.
reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.
an organism that obtains nutrients from other organisms in a harmful way that doesn't cause immediate death

having more than one female as a mate at one time
breeding is confined to a particular season
offspring are all produced in a single group (litter, clutch, etc.), after which the parent usually dies. Semelparous organisms often only live through a single season/year (or other periodic change in conditions) but may live for many seasons. In both cases reproduction occurs as a single investment of energy in offspring, with no future chance for investment in reproduction.
