No one knows better than golden-eyes what her children are capable of doing when on a foraging tour. For this reason she places her eggs high on silken stalks (Fig. 345). If she laid them on the leaf close together, the first aphis-lion hatched would not give the other members of his family a chance to open their eyes, nor to know how pleasant it is to live on a green leaf. As it is he walks down the silken stalk and finds himself among the aphids. Then, when he has proved himself the gardener's friend by devouring a great many of the small green insects, he spins a pearly white cocoon and out of this comes a lace-winged-fly with glistening golden eyes. If one of these dainty creatures comes to live in your terrarium, you may notice some day that it has a disagreeable odor. This is a characteristic that many insects possess, and owing to it the birds do not like to eat them. There is another insect out in the garden that ought to be an inmate of every terrarium this fall, the green cabbage-worm. Some Junior gardeners will object to calling this a friendly little neighbor, but you will find that he will teach you many new things, in this way proving himself friendly to you as a naturalist. You must remember that these green caterpillars did not know that you had planted the garden in which they worked destruction. They did not know that you wanted to send the very best cabbage to the State fair. They knew only that when they opened their eyes they were on a green leaf and it was good to eat. Probably you will find the eggs of the cabbage butterfly on the under side of the leaves. Then you can feed the young caterpillars when they hatch. They will, of course, prefer cabbage leaves. If you miss them some day, search in the terrarium for the chrysalids into which they have changed. These chrysalids sometimes imitate the color of the support from which they hang, and you may have difficulty in finding them. For this reason it may be well to keep one of the caterpillars under a lamp chimney, the top of which has been covered with mosquito netting (Fig. 342), so that you may know how the chrysalids look. The cabbage butterflies are familiar to most boys and girls; yet as they come out of the chrysalid state in your terrarium, you will be able to observe them more closely. Notice that the wings are dull white on the upper sides, while on the under side the apex of the fore wings and the entire surface of the hind wings are pale lemon yellow. In the female you will find that there are two black spots besides the tip on each of the fore wings, and in the male there is but one. [Illustration: _Fig. 342. An insect cage._] Now that I have put you in the way to find a few members of the insect world for your terrarium, I am going to ask you to think about some other outdoor-folk that naturalists learn to like.
