Tlie moth is well known in Germanj^ where it is called tlie Harlequin Moth (3). It is also common in France. Tne damage is done by the small caterpillars in the spring, but tliej' are usually undetected until they are nearing maturity, and then, the foliage becoming badly eaten, remedies are adopted. The damage, however, is mainly done to the opening Ijuds and young leaves. Infestation may come from woods and hedgerows. The cater- pillars have a very varied diet otherwise than cultivated fruit, for we frequently find them swarming on hazel, .sloe, maple, spindle and otlier trees. LiFE-HlSTOEY AND This motli belongs to tlie same family as the Winter Moth, namely, the Gcoriutrklcc, the caterpillars being " Loopers" or " ; The moth is about 1^ inch in wing expanse, but the size is most variable.
