To speak here of mother-love were, I think, extravagant.

The Lycosa's affection for her offspring hardly surpasses that of the plant, which is unacquainted with any tender feeling and nevertheless bestows the nicest and most delicate care upon its seeds.

The animal, in many cases, knows no other sense of motherhood.

There is no question here of real maternal affection.
I have described elsewhere the prowess of the Copris watching over cells that are not her handiwork and do not contain her offspring.
