- 1 Order, Coleoptera, (Beetles). Many beetles are colored so as
- 2 to resemble the surfaces which they habitually frequent, and they thus
- 3 escape detection by their enemies. Other species, for instance, diamond-beetles, are ornamented
- 4 with splendid colors, which are often arranged in stripes, spots, crosses,
- 5 and other elegant patterns. Such colors can hardly serve directly as a protection, except in the case
- 6 of certain flower-feeding species; but they may serve as a warning or means of
- 7 recognition, on the same principle as the
- 8 phosphorescence of the glow-worm.
- 9 As with beetles the colors of the two sexes are generally alike, we have
- 10 no evidence that they have been gained through sexual selection; but this is
- 11 at least possible, for they may have been developed in one sex and then
- 12 transferred to the other; and this view is even in some degree probable
- 13 in those groups which possess other well-marked secondary
- 14 sexual characters. Blind beetles, which cannot, of course, behold each
- 15 other's beauty, never, as I hear from Mr. Waterhouse, Jr., exhibit bright
- 16 colors, though they often have polished coats; but the explanation of their
- 17 obscurity may be that they generally inhabit caves and other obscure stations.
