Proceedings of the Entomological Society of Washington. 105:246-248. Interpretive Summary: Invasive plant-feeding wasps in the United States can cause extensive damage to agricultural crops, ornamental plants, and forests. Four species which were originally found in New York and New England have now been found as far south as Virginia and Maryland. One is the introduced apple sawfly, and another feeds on ornamental roses. This information will alert federal and state agricultural agents to be on the lookout for further spread of these pests and will be of use to regulatory personnel interested in their control.
Technical Abstract: New southerly distributions in Maryland, Virginia, and West Virginia are presented for four species of invasive sawflies in the United States. Given are the first records of the European apple sawfly, Hoplocampa testudinea (Klug) from Maryland; a rose sawfly, Allantus viennensis (Schrank), from Virginia and West Virginia; and Nesoselandria morio (Fabricius) and Heptamelus ochroleucus (Stephens), which feed on moss and ferns, respectively, from Maryland and Virginia.
