A Pomace Fly Drosophila ampelophila Loew. et al. Pomace flies of various species were bred in great numbersfrom blueberries placed in cages in the insectary, as soon as thefruit became a trifle old and had lost its firmness. Unlessstored berries were packed securely and guarded against theattack of these flies they might prove to be a very serious pest. In two cases in fresh berries brought in from the field thev/riter has found white dipterous larvae which he believes wereDrosophila sp., but it is seldom, if ever, that Drosophila attacksthe fresh fruit. Care should be taken not to confuse this insect with Rhago-letis. Fortunately larva, puparium and adults are all very muchunlike. This species is figured in
