Abstract

Scymnus (Pullus) suturalis Thunberg is a Palearctic species that occurs on conifers, where it is reported to feed on aphids (I. Hodek. 1973. Biology of Coccinellidae. Academia, Czechoslovak Academy of Science. Prague). The occurrence of S. suturalis in North America was first reported by R.D. Gordon (1982. Proc. Entomol. Soc. Wash. 84:250-25 5) who distinguished specimens collected in New York and Pennsylvania from a similar western species, Scymnus (Pullus) coniferarum Crotch.
