- n. A butterfly of the genus
Sorry, no etymologies found.
Then there is the curious leaf-butterfly, which has a marvellous resemblance to a dead leaf with its wings folded over the back and showing the underside only, the leaf-stalk veins being excellently mimicked.
The leaf-butterfly _Kallima_, conspicuously coloured on its upper surface, is like a withered leaf when it settles down and shows the under side of its wings.
And it is to be noted that it is by no means only external parts that are changed; internal parts are _always_ modified at the same time -- for instance, the delicate elements of the nervous system on which depend the _instinct_ of the insect to hold its wings, when at rest, in a perfectly definite position, which, in the leaf-butterfly, has the effect of bringing the two pieces on which the marking occurs on the anterior and posterior wing into the same direction, and thus displaying as a whole the fine curve of the midrib on the seeming leaf.
