iVM TURE S CALENDAR 109 



white butterflies are laying the eggs from May 23 



which the cabbage worms are to come. ' 



Along the higluvays and in open glades 

 the winter butterflies are disporting 

 themselves, enjoying the warm sunshine 

 that rewards them for the long, cold 

 waiting in crevices and cracks of rocks 

 and logs. Late in the month some but- 

 terflies tiiat have wintered over as chrys- 

 alids make their appearance, fresh from 

 their mummy-cases. In the orchard the 

 canker-worms and the bud-worms feed 

 freely on the young and unfolding leaves, 



while in the meadows a host of insects . 



are at work among the grasses. The 

 water insects, too, are again active wan- 

 dering about among the shadows on the 

 rocky bottom, swimming freely through 

 the water, or playing blithely on its sur- 

 face.
