winter in the ground as pupae and emerge in July to lay 

 their eggs on the leaves. 



The Cabbage Butterfly, Pieris rapa, is our commonest 

 white butterfly. The females have two black spots on the 

 fore wing, while the males have but one. This is one of 

 the best forms for the pupils to rear. The writer has 

 counted 465 ovules in a single specimen, which shows 

 what a power for damage one little butterfly may be. But 

 this is possibly the only one of our common butterflies 

 that should be destroyed wherever seen. 



The Cabbage Plusia, Plusia brassicce. — The larva is a 

 green, striped, measuring or looping caterpillar. The 

 moth is dark smoky gray and flies and lays its eggs at 

 night. 



The Corn Worm, or Bollwonn, Heliothis armigera. — This 

 insect attacks the two great staples, corn and cotton, 

 and is also a common pest on tomatoes, peas, and beans. 

 When numerous enough to demand study, the larvae, vary- 

 ing from grass green to dark brown, with a yellow stripe 

 along each side, may be found in the tips of the ears of 

 corn. When fully grown — they are about one and one- 

 half inches long — they bury themselves in the ground. 

 Here they transform into brown chrysalids and emerge, 

 after three or four weeks, as clay-yellow moths. 



The Army Worm, Leucania unipuncta. 



The Squash Bug, Anasa tristis. — This is a good example 

 of a true bug, but a serious garden pest for all plants of 

 the cucumber family. The eggs are yellowish brown or 

 bronze in color, large and conspicuous, and neatly spaced 

 in groups of twenty to forty on the leaves or stems of the 

 food plant.
