Note AD — Chapter IV · VARIATION AND NATURAL SELECTION.

Many other instances might be added. The hornet clear-wing moth (Sphecia apiformis) mimics the hornet or wasp; the narrow-bordered bee-hawk moth (Sesia bombyliformis) mimics a bumble-bee. These insects may be seen in the lepidoptera drawers in the Natural History Museum. But perhaps the most wonderful instance of insect-mimicry is that observed by Mr. W. L. Sclater, and given by Mr. E. B. Poulton, in his "Colours of Animals" (p. 252), where a (probably) homopterous insect mimics a leaf-cutting ant, together with its leafy burden—a membranous expansion in the mimic closely resembling the piece of leaf carried by the particular kind of ant he resembles.
