BUTTERFLIES AND MOTHS IN AUTUMN 69 



of the green caterpillars of the small cabbage white climb 

 under lintels and copings in September to undergo their 

 change, their end often comes suddenly. Their habit is to 

 bind themselves to their support by silken bands round the 

 middle and at the tail, and so to hang safely in the helpless 

 pupal state. But dissolution often comes upon them before 

 the operation is complete ; and instead of the pale angular 

 chrysalis, we find in a few days' time a shrivelled greenish 

 cerement and a cluster of ichneumon pupae like small eggs.
