Eger, J.E. Jr. and Baranowski, R.M. 2002. Diolcus variegatus (Heteroptera: Pentatomoidea: Scutelleridae), a Caribbean species established in South Florida. Florida Entomologist 85(1): pp. 267-269.
In August 2001, numerous individuals of Diolcus variegatus (Heteroptera: Pentatomoidea: Scutelleridae) were found feeding on the fruit of Malvastrum corchorifolium (Malvaceae), or false mallow, in Homestead County, Florida (Miami). This species appears to be well established in South Florida. Its previous distribution is reported as Cuba, the Cayman Islands, Dominican Republic, Haiti, and Jamaica. Two species of Diolcus are native to the US (D. chrysorrhoeus and D. irroratus), but this is the first report of D. variegatus from the US.
