Notes: | Label source: Life History - The caterpillars of these two moths are always more or less present in hop plantations, and are hurtful to the extent of their numbers: some years they are abundant. Orgyia pudibunda feeds on several kinds of trees besides h, op, especially oak & birch. The caterpillars may be found from June to the middle of August, when each spins a few leaves together and changes to a chrysalis, the moths coming out the following May. O.antiqua is a very general feeder, and besides hop, is, at times very hurtful to fruit trees. The female is nearly wingless, and lays its eggs on the outside of the cocoon from which it emerges, and then dies. These eggs do not all hatch at once, but a few come out at intervals extending over a period of 10 w, eeks, so that the insect is found in all stages throughout the summer. The cocoons are usually spun on palings or on the trunks of trees. The damage they do to the plants is caused by pieces being out of the leaves. Prevention and Remedies: as both caterp, illars and moths are conspicuous objects, the former may easily be seen and picked off, or shaken down and destroyed, and the moths may be found in the morning freshly emerged and drying their wings. The cocoons of O. antiqua are readily seen, and may be, collected by children and destroyed; many of those of pudibunda may be destroyed by raking up winter leaves and rubbish and burning. Various stages in the life cycle are shown. |
