But Arsinoe only remembered these things to-day as a butterfly sporting in the sun may remember the hideous pupa-case that it has burst and left behind it. Radiant with happy excitement, she was led to her seat with her young companion, the black-haired daughter of the shipwright.

Bouché states that the larva is cylindrical, rounded posteriorly, smooth and shining, fleshy, and yellowish white, and four lines long. The pupa-case, or puparium, is dark reddish-brown, and three lines in length. It remains in the pupa state from eight to fourteen days. The flesh fly, Musca Cæsar, or the Blue-bottle fly, feeds upon decaying animal matter.
He told her how he had begun life as a caterpillar and then, one day, when he had shed his last caterpillar skin, he came out a pupa or chrysalis. "At the end of a few weeks," he continued, "I woke up out of my dark sleep and broke through the wrappings or pupa-case. I can't tell you, Maya, what a feeling comes over you when, after a time like that, you suddenly see the sun again.
But then she wanted to know how the butterfly's large wings could grow in the small space of the pupa-case. Fred explained. "The wings are delicately folded together like the petals of a flower in the bud. When the weather is bright and warm, the flower must open, it cannot help itself, and its petals unfold. So with my wings, they were folded up, then unfolded.
The Merodon Narcissa probably lives in the soil, or in rotten wood, as the pupa-case has no respiratory tube, having instead a very short, sessile, truncated tube, scarcely as long as it is thick. The case itself is cylindrical, and rounded alike at each end. We now come to the Bot flies, which are among the most extraordinary, in their habits, of all insects.

The larva is found during the month of May, and also in summer, living in tumors on the backs of cattle. When fully grown, which is generally in July, they make their way out and fall to the ground, and live in the pupa-case from twenty-six to thirty days, the fly appearing from May until September. It is found all over the world.
