(Uranotaenia sapphirina)
Uranotaenia sapphirina is a species of mosquito in the family Culicidae. Uranotaenia sapphirina is a common species throughout Eastern North America. It was found from an experiment that unlike Uranotaenia lowii which feeds only on anurans (frogs and toads), Uranotaenia sapphirina exclusively fed on annelid hosts such as earthworm and leeches. Uranotaenia is a genus of mosquitoes containing at least 270 species. It is the only member of the tribe Uranotaeniini.
