From Project Gutenberg

From Project Gutenberg

Geologically the facts oblige us to begin with Cryptogamous plants and mandibulate insects; and out of the desire of insects for non-existent honey, and the adaptations of plants to the requirements of non-existent suctorial apparatus, we have to evolve the marvellous complexity of floral form and colouring, and the exquisitely delicate apparatus of the mouths of haustellate insects.

From Project Gutenberg

From Project Gutenberg

The bees and wasps, and the butterflies and moths, are little likely to have been present where there were scarcely any flowering plants; but such groups as those of the two-winged flies, the plant-bugs and the ants, we might have expected, but 148for the fact of their being highly specialised forms, and for that reason likely to have appeared later.53 There are, indeed, as yet no haustellate or suctorial insects known in this early period.
