About Pachysomoides stupidus
Pachysomoides stupidus develops as a parasitoid of paper-wasp larvae in the genus Polistes.
Ecology and introduction history
Pachysomoides stupidus develops as a parasitoid of paper-wasp larvae in the genus Polistes. It is a wasp exploiting another wasp’s brood, rather than a member of the paper-wasp colony. Hawaiian records include Kauaʻi. The cited account regards it as an accidental immigrant. A specimen record does not show how frequently local nests are attacked, or establish equivalent susceptibility for every Polistes species.
Kauaʻi occurrence and evidence

Evidence limits
