Extract

Until now this family has been known only through one species Nymphomyia alba Tokunaga, found in Japan in 1932. The specimens taken in New Brunswick and shown in the exhibit differ strikingly from Nymphomyia and represent a new genus.

With one exception, the thirty-eight individuals recovered from collections to date, were taken by fine-mesh screens set in the rapids of a small stream. These had been placed to catch casualties among aquatic insects drifting downstream following spraying of the adjacent forest with DDT. The spraying operation was of an experimental nature, carried out cooperatively by Forest Protection Limited, the Chemical Control Section, Canada Department of Forestry and the Fisheries Research Board of Canada.
