THE GREEN PEACH APHIS. {Myzus sp.) Order: Hemiptera. Sub-order: Homoptera. Family: Aphididce. This species is even more dreaded by growers thanthe so-called black Peach Aphis, as it appears later in theseason, when the trees are in leaf; and as it curls theleaves by perforating them with its beak-like rostrum(see Fig. 1), it renders the labour of spraying muchmore difficult, and the chances of destroying the insectsmore remote. The Green Peach Aphis in its habits is much like thatof the black one, but the shape and colour of the insectsin their various stages are different (see Plate XV.). When the aphides leave the tree, which, as a rule, theydo about the end of November, or even late in December,according to seasons, locality, &c, the young and perfectinsects also congregate around the base of the roots,whilst
