In the Zoo

Edward George Boulenger, Animal Ways, Londres, Ward, Lock & Co, 1931, p. 102.

In the Zoo Insect house the larva of the caddis fly builds an elegant tubular house from shell and gravels, and when provided with coloured beads, will use them with decorative effects.

Référence au Zoo de Londres ? Boulenger étant le directeur du Zoological Society’s Aquarium.
