Copidosoma floridanum is a species of wasp in the family Encyrtidae which is primarily a parasitoid of moths in the subfamily Plusiinae.

So, as a result of eusocial progeny allocation and a distinctive type of clonal development in parasitized hosts, polyembryonic wasps including C. floridanum are able to thrive.

[9] In his study, Giron argues that soldier aggression in this wasp species is inversely related to competitors' genetic relatedness, without respect to levels of resource competition.

[9] In a later study, Giron sought to differentiate between the aggression of female and male soldiers, finding that the latter group is non-aggressive toward all competitors.

Competition for resources limits how many adult wasps can emerge from the host; this indicates that negative relatedness likely exists within the brood.

C. floridanum gain interspecific competitive advantage over other competitors, including Glyptapanteles pallipes and Microplitis demolitor, primarily due to the presence of their soldier caste, whose fitness is limited to the survival of their clonal siblings.

Uka studied the interspecific competition between C. floridanum male broods and G. pallipes in order to elucidate the defensive strategies of the former group.

First off, they secrete a physiologically suppressive factor from in their labial glands as embryos or even in the tissue of the host and steadily supplied to the hemolymph.

This is an effective evolutionary strategy, as other approaches could leave obvious wounds on the host cells, alerting competitors to the presence of this wasp species.

[15] More specifically, odorant binding proteins (OBPs) are utilized for kin recognition, along with the likely usage of toxin-like and SP genes in the ability of soldiers to murder competitors or as immune defense against potential pathogens.
