Chapter XXI.

1. Some of the bombycia[179] form an angular cell of mud, which they attach to a stone or something else, and smear with a kind of transparent substance; this is so very thick and hard, that it can scarcely be broken with the blow of a spear. In this they deposit their ova, and the white maggots are contained in a black membrane; and wax is formed in the mud without any membrane, this wax is much more yellow than that of bees.

2. The ants also have sexual intercourse, and produce maggots which they do not attach to anything. As these grow, they change from small round things to long articulated beings. The season for their production is in the spring.

3. The land-scorpions also bring forth many egg-like maggots, upon which they incubate. When the young ones are perfect, they drive out and destroy their parents like spiders, for they are frequently eleven in number.
