There is no difficulty here; the Mantis is quite indifferent to imprisonment under glass, provided it is well fed.

Offer it a tasty diet, feed it daily, and it will feel but little regret for its native thickets.
For cages I use a dozen large covers of wire gauze, such as are used in the larder to protect meat from the flies.

Each rests upon a tray full of sand.

A dry tuft of thyme and a flat stone on which the eggs may be laid later on complete the furnishing of such a dwelling.

These cages are placed in a row on the large table in my entomological laboratory, where the sun shines on them during the greater part of the day.
