Lepidoptera The Marsh Ringlet Butterfly – Canonympha Typhon
The upper surface of this butterfly is shown in the first figure of
This is generally spoken of as a northerner, its chief localities being in the mountainous parts of Scotland and the elevated districts of the north of England, but in Ireland it extends to the southern ranges. Its haunts are elevated moors and marshy heaths, where its food plant-the beak-rush (Rhyncospora alba)-abounds, and it is on the wing from the end of June to August or September.
The caterpillar is green, with five longitudinal stripes-one dark one, bordered with yellow, down the middle of the back, and two pale yellow ones on each side. It is a hybernator, and is full grown about the end of May, when it suspends itself by the hindmost claspers to a silken carpet, and changes to a green chrysalis with pale brown wing cases.
