CATERPILLER NESTS AND LARV^. 



1. Cocoon of the Anaphe Moth. This is spun of silk by all in common. When 

 finished each spins a cocoon for itself within the outer case. 



2. Silken web of the caterpillars of the Small Ermine moth. Here again all the 

 members of the community work in common to fashion the house, which in this 

 ■case is used as a shelter when feeding, 



3. Caterpillar and chrysalis of the Orange-tip Butterfly. Note the silken girdle 

 by which the body is kept in place during the winter sleep.
