"[72]
One more example of a protected caterpillar must be given. Mr. A.
Everett, writing from Sarawak, Borneo, says: "I had a caterpillar
brought me, which, being mixed by my boy with some other things, I took
to be a bit of moss with two exquisite pinky-white seed-capsules; but I
soon saw that it moved, and examining it more closely found out its real
character: it is covered with hair, with two little pink spots on the
upper surface, the general hue being more green. Its motions are very
slow, and when eating the head is withdrawn beneath a fleshy mobile
hood, so that the action of feeding does not produce any movement
externally. It was found in the limestone hills at Busan, the situation
of all others where mosses are most plentiful and delicate, and where
they partially clothe most of the protruding masses of rock."
_How these Imitations have been Produced._
To many persons it will seem impossible that such beautiful and detailed
resemblances as those now described--and these are only samples of
thousands that occur in all parts of the world--can have been brought
about by the preservation of accidental useful variations.
