An investigation of the insects living upon the fruit trees and shrubs growing in the neighbourhood of Treesbank, Man., was carried on during the summers of 1924; 1925 and 1926. The following list arranged by orders includes all the insects observed, with notes on their food plants and general time of occurrence in the adult stage, together with those species found already breeding on cultivated fruits.
