DRAGON FLY.

Of these flies, which are called by many Spindles, there are various
species. They all have two very large eyes, covering the whole surface
of the head. They fly very swiftly, and prey upon the wing, clearing the
air of innumerable little flies. The great ones live about water, but
the smaller are common among hedges, and about gardens.




BUTTERFLY.

Of butterflies there are many kinds. How wonderful the various changes
of this class of insects! The butterflies lay their eggs: from these
hatch out worms or caterpillars, which change their skins several times,
and, finally, become aureliae, chrysales, or silkworms, out of which
come the beautiful butterflies.
