Extract

During the latter part of August and early in September, 1950, dolichopodid flies were observed feeding on adults of the European red mite on apple foliage, untreated with acaricides, in the Science Service orchard, Harrow, Ontario.

Specimens were determined by Mr. J. R. Vockeroth, Systematic Entomology, Division of Entomology, Ottawa, as follows: Condylostylus sipho (Say), Laxina nigrofemoratus (Wlk.), and Diaphorus or Chrysotus sp.
