Hybernating moths may also be met with, on the wing if the weather is mild, or sleeping in their sheltered nooks during the frosts. These include several _Noctuae_--_Auricoma_, _Lithargyria_, _Suffusa_, _Vaccinii_, _Spadicea_, _Erythrocephala_, _Satellitia_, _Rubiginea_, _Croceago_, _Vetusta_, _Exoleta_, _Ornithopus_, _Furcifera_, _Semibrunnea_, _Socia_, and _Libatrix_; and also a few _Geometrae_--_Zonaria_, _Fluviata_, _Dubitata_, _Siterata_, and _Miata_. In addition to these hybernating insects, the collector may examine tree trunks and fences for the Early Moth (_Rupicapraria_), and late specimens of the Winter Moth (_Brumata_); and towards the end of the month he may expect to meet with fresh specimens of the Pale Brindled Beauty (_Pedaria_) and the Spring Usher (_Leucophaearia_). A few of the _Tineae_ may also be seen. The net need not be used at all during the colder months of the year, as the moths are easily taken in pill boxes from the trunks and fences on which they rest. Pupa digging may be carried on throughout the month if the weather is sufficiently mild, but it is of no use attempting this during a frost. Hybernating larvae may also be searched out of their winter quarters if the collector does not mind giving them the attention they require; but, as a rule, it is better to wait till they themselves start out to feed in the spring, at which time all their food plants are showing leaf. FEBRUARY Our remarks under 'January' concerning pupa digging and other work apply equally well to this month. The same hybernating butterflies and moths may be looked for; and, in addition to _Pedaria_, _Leucophaearia_, and _Rupicapraria_, which now appear more plentifully, the following species will probably be seen: Small Eggar (_Lanestris_) Small Brindled Beauty (_Hispidaria_) Oak Beauty (_Strataria_) Dotted Border (_Marginaria_) March Moth (_AEscularia_) About half a dozen species of the _Tineae_ will also have made their appearance before the end of the month. MARCH Many of the hybernating larvae will come out during March if the weather is mild, and commence to feed; and the young caterpillars will begin to appear from the eggs of the early moths already named. This is consequently a good time to commence the search for larvae if you intend to go in for rearing. During the daytime some may be beaten from the boughs of trees and shrubs; and those which feed on low plants, being generally nocturnal in their habits, should be searched for in the evening, after dark, with the aid of a lantern. The hybernating butterflies are now flying more freely than before, and, if the weather is bright and warm for the time of year, a few freshly emerged species may be seen. These may possibly include: Large White (_Brassicae_) Small White (_Rapae_) Green-veined White (_Napi_) Holly Blue (_Argiolus_)
