THE PHYLLOXERA

“In our talks on ants a few words were said concerning their milch-cows, plant-lice. You haven’t forgotten those curious herds with udders in the form of two little tubes that emit, from time to time, a sweetened liquid. The ant comes and milks these cows, caressing them as it does so with its two antennæ. It fills itself with their milk, making its stomach serve the purpose of a milk-pail, and then runs back, all bursting with the delicious fluid, to disgorge it into the nurslings’ mouths.
