found covered with white cocoons of the 

 parasites. 



Pieris raped, the Cabhage Butterfly, is another 

 common pest in the garden. It is yellow with 

 black markings. The male has one black spot 

 on each fore wing, and the female two. The 

 metamorphosis takes place in such a short time 

 that it offers one of the best opportunities for 

 studying the life history of an insect. There are 

 several broods a year. The eggs are laid on the 

 leaves. The green larvae attain their growth in 

 two weeks, and change into chrysalids from 

 which the butterflies emerge in ten days. Spray- 

 ing the leaves with poison is dangerous, and it 

 is therefore better to destroy the butterflies, 

 though this is not a pleasant thing to recommend. 



Diabrotica vittata, the Striped Cucumber- 

 Beetle, is a very familiar inhabitant of the gar- 

 den. It seems to be waiting for the vines to 

 come up, for as soon as the tiny leaves appear 

 above ground the beetles are there ready for 

 work. Paris green and tobacco-dust are effect- 

 ive remedies. 



Anas a tristis — Squash-Bug — ^hibernates, ap- 

 pears in the spring, and lays eggs on the tender 

 sprouts of squash and pumpkin vines, and some- 

 times entirely destroy them. Its near relative is 

 the Stink-Bug, the creature which often gives to 

 raspberries and other berries a disagreeable taste.
