The butterflies seen in spring and early summer, up to, say, the beginning of July, are supposed to have wintered in this country, but there is no positive evidence, that I can find, that the butterfly does hibernate here. It is, however, most probable that they are arrivals from abroad. The species is found throughout Europe and North Africa, Northern Asia, and North America, and it may be suspected of migration, although there is, perhaps, not such conclusive evidence on this point as in the case of its cousin, the Painted Lady. Anyway, unless we admit immigration, it seems difficult to understand why this butterfly should suddenly become common in some British localities from which it has been almost or quite absent for several years. Again, we rarely hear of butterflies moving about at night, but the Red Admiral, as well as the Painted Lady, are known to do this. If it does hibernate in this country it is very late in taking up winter quarters, as it is seen on the wing at the end of October, and sometimes even in November; it has also been known to emerge from the chrysalis in the latter month. It does not appear in the spring with other hibernating species, and is rarely seen before the end of May, but June seems to be about the normal time. In the autumn it is fond of making excursions into the flower garden and the orchard, where it takes toll from flower and fruit, an over-ripe pear or plum being its special weakness. The blossoms of ivy, hop, thistle, teazle, etc., are attractive, but a tree-stem that has been bored by the caterpillar of the goat moth will be visited by nearly every Red Admiral in the district. One observer mentions that he once saw quite thirty of these butterflies gathered around one wounded birch tree on Wimbledon Common. There was not room for all to imbibe at the same time, but those unable to satisfy their desire at the moment were content to sit around and await a favourable opportunity of joining in the feast. The seductive fluid obtained from such trees is evidently more potent than the nectar from flowers, as under its influence the insect is so listless that it may be taken up between the finger and thumb. Its range extends throughout the British Islands, and seems to be very similar to that of the Painted Lady. The Silver-washed Fritillary (_Argynnis paphia_).
