Lepidoptera The High-brown Fritillary Butterfly – Argynnis Adippe
The upper side of this butterfly is so much like that of Aglaia that it would be difficult indeed to give a written description of one that did not almost equally well apply to the other; so we look to the under surface for the chief marks by which we can distinguish between them.

This butterfly is common in open spaces of woods in many parts of England, more particularly in the south, and seems to be also fond of hilly heaths and moors.
It is on the wing in July, and, towards the end of this month and in the beginning of August, the eggs are laid on the leaves of the dog violet (Viola canina) and heartsease (V. tricolor).
The young caterpillar emerges about two weeks later, and feeds only for a short time before it seeks out its winter quarters among the dead leaves at the root of its food plant. The feeding is resumed in the spring, and continued till the month of June, when it is fully grown. At this time it is about an inch and a half long. Its head is black, and its body pinkish brown. A white line extends down the back, but is interrupted by several black marks. The spines, of which there are six rows, are white, with pinkish tips.
