The wings, by many morphologists, are not included in the category of "appendages"; they apparently, however, differ but little in their nature from legs, both being outgrowths of the integument; the wings are, however, always post-embryonic in actual appearance, even when their rudiments can be detected in the larva. No insect is hatched from the egg in the wing-bearing form.
