Chapter III · THE BRITISH BUTTERFLIES DESCRIBED (continued 2)

This is a very local species, and I am afraid, to judge from reports, becoming rarer. The south and south-eastern counties are the favoured localities.

The Milkweed Butterfly (Danais Erippus; variety, Archippus), Plate VIII., Fig. 3.—This is an American species, but an occasional visitor to our shores, and, as it is a strong-flying species with the bump of adventure abnormally developed, it is now met with in many lands where it was at one time unknown. I have large fine specimens from Canada, so it can stand the rigours of the Canadian winter; and if it should find a suitable food-plant for the caterpillars here, we may hope, in the near future, to add this fine butterfly to the select little band of British butterflies.
