Cacopsylla peregrina (Foerster) (Sternorrhyncha: Psylloidea: Psyllidae): First U.S. records of an old world specialist on hawthorns (Crataegus spp.)
Proceedings of the Entomological Society of Washington 103 (1), 103-109
Abstract: Known previously from British Columbia, Canada, the Palearctic Cacopsylla peregrina (Foerster) is reported from California, Oregon, and Washington as the first U.S. records for this psyllid. Detected in 1999 in Washington on English hawthorn (Crataegus monogyna Jacq.), which has been introduced and planted as an ornamental in North America, C. peregrina is thought to have been accidentally introduced with hawthorn nursery stock from Europe. A brief taxonomic description of the adult and this psyllid's Old World distribution and bionomics are provided.
