coccids

In the coccids, the green particles grow into a kind of yeast that lives within the insect.

The term "mutualism" as applied to these cases means, of course, that the aphids, coccids, and membracids are of service to the ants and in turn profit by the companionship of these more active and aggressive insects.

The solicitude of the ants not only envelops the adult aphids and coccids, but extends also to their eggs and young.

This is also exhibited by all ants that harbor root-aphids and root-coccids in their nests.

In the last-named order, however, we find in certain families marked divergence between larva and imago, for example in the cicads, whose larvae live underground, while in the coccids, whose males are highly specialised and females degraded, there succeeds to the larva -- very like the young stage in allied families -- a resting instar, which in the case of the male, suggests comparison with the pupa of a moth or beetle.

In the case of some of the insects reviewed in the last three chapters, the may-flies and cicads for example, a marked difference between the larva and the imago has been noticed; in others, as the coccids, we find a resting instar before the winged condition is assumed, suggesting the pupal stage in the butterfly's life-story.

In the life-histories of cicads and coccids, then, there are some features which recall those of the caterpillar's transformation into the butterfly.
