Lepidoptera The Small Ringlet Butterfly – Erebia Epiphron
On account of the very limited range of this butterfly, only those who have the opportunity of visiting its haunts can have any practical acquaintance with its natural history. It is almost exclusively confined to the lake district in England, to a few mountainous localities in Scotland, and to one or two similar localities in Ireland. Its strong partiality for elevated situations has earned for it the popular name of Mountain Ringlet.
The colour of the upper surface (Plate V, fig. 3) is a dark brown, with a broad band of rusty brown, parallel with the hind margin of each wing, and broken by the wing rays. Each division of these bands has often a black central spot, but frequently these are entirely absent. The colouring of the under side is very similar but less defined, and the rusty spots of the hind wings are very small.
The butterfly is out in June and July. The caterpillars, which are green, with white stripes along the sides, feed on various grasses. They hybernate during the winter, and change to the chrysalis state in the following May or June.
