Although a high flier, yet it very frequently alights on the trunks of trees.

On these occasions its head is invariably placed downwards; and its wings are expanded in a horizontal plane, instead of being folded vertically, as is commonly the case.

This is the only butterfly which I have ever seen that uses its legs for running.

Not being aware of this fact, the insect, more than once, as I cautiously approached with my forceps, shuffled on one side just as the instrument was on the point of closing, and thus escaped.

But a far more singular fact is the power which this species possesses of making a noise.
