The cabbage powder-wmged moth (Aleyrodes proletella L.—the Aleyrodes elielidonii of Lat- reille) often commits sad havoc amongst the cabbage and broccoli crops in its fly state during the month of November. They begin to make their appearance in May, and live under the leaves where they are hatched, abounding during the months of June, July, and August. They are thus described in " Gardeners' Chro- nicle " for 1851, p. 837 : " The aleyrodes is a minute fly, covered with white powder. The females have been observed about midsummer to remain quite quiet on a leaf for several days when about to lay their eggs; and when they had left the spot where they had rested, a small circular space covered with white powder was observable, around which were irregularly de- posited from 9 to 14 eggs. These eggs are transparent, but afterwards turning to a yellow- ish tint. They hatch in about 12 days, and the young larvse immediately run a short distance to spread themselves more about the leaf, but in a few hours a scale is formed over them, so that they look like little tortoises or cocci, and exhibit no signs of life. The colour is almost white, with two yellow spots behind. They are not absolutely stationary, but only move very short distances as they increase in size, being furnished with six pectoral legs.
