Abstract
THIS year the noctuid Plusia gamma has been more abundant in Denmark than at any time since 1905. It is likely that the swarms arrived here in June; the first report of damage caused by the larvæ came from the southern part of Denmark, and was followed by similar reports from more northern parts, thus closely corresponding to the seasonal progression recorded in England1. The adults appeared about August 1.
