Then there are the Hemerobii; or golden-eyes, whose larvae are called Aphis-lions (fig. 69), a ferocious fa- mily nearly related to the ant-lions. Another set of insects are parasitic, and deposit minute eggs in the old aphides, which then change to dull ochreous, horny objects, sticking to the leaves on which they had fed, frequently exhi- biting a hole in their sides, from where the parasitic little ichneumon called Aphidius had ; The earwig and ant wage constant war against them, and soft-billed birds work wonderful destruction amongst them; and to these we may add, as valuable to man— The Aphis-lion, fig. 69, of which there are numerous species.
