EGGS OF CATERPILLARS.

cannot fly, slie makes use of the materials within 
her reach, and what do yon think she does ? 
Close by her, lies the cocoon or case, that she 
has just crept out of. Nothing can 
he more luxurious than this silken 
couch, and so the moth seems to 
think. She fixes her eggs to the 
outside of the cocoon; and as the 
cocoon itself is always suspended in v ^£ er 
some sheltered place, beneath the 
arm of a tree, or behind a wall or gate, the 
eggs are kept very warm, and hatched all the 
sooner. 
But the mother moth or butterfly seems also to 
know what the habits of the caterpillar will he. 
Some caterpillars choose to live each one by 
itself, and then it is said to he of the solitary 
species. Others will feed together, and form 
colonies, having hut one nest in common, and 
then they are of 66 the social kind.” 
This is always provided for hy the mother. If 
her eggs are of the solitary species, she will often 
lay hut one on a leaf, and allow plenty of space 
for the little hermit to indulge its unsociable 
disposition. But should they he of the social 
kind, she lays them in a group, or packs them 
into a solid cone, as we have seen the gypsey 
moth do.
