White Butterfly.
A Garden Corner.
QTHERE ARE three varieties of white butterflies differing in size and appearance. All are inimical to cabbage growers, the worst of all being the large, white Pieridae Brassica, which is apparently getting common throughout Canterbury. The specimen shown here was captured in a Redcliffs garden. As thev are frequently reported from North Canterbury, it would appear as if they had jumped Cook Strait just as did the fireblight.
.... The female lays her yellow eggs in clusters on the cabbage leaves awd the caterpillars are so voracious that they quicklv eat the leaves to shreds. In a month’s time the grubs turn to chrysalids hanging from walls, trees or fences during the winter. Control can be effected by collecting all egg masses and chrysalids, and of course, swatting the mature butterfly on sight; spraying the plants with weak salt and water is said to be effective. With young plants, arsenic spraying would be good, but this can hardly be used on plants approaching maturity. T. D. LENNIE.
