RAGGING THE BAGWORM. 



While the bagworm has been more or less prevalent in St. 

 Louis for a number of years, the unusual number of these pests 

 last spring, with the resulting cocoons, makes it probable that 

 a considerable amount of damage to the trees may be antici- 

 pated during the coming season unless some systematic cam- 

 paign is devised against them. The curious habit of the cater- 

 pillar of crawling about in a bag-like case makes it unusually 

 conspicuous, and there are few trees in the city on which a 

 careful inspection will not reveal, attached to the twigs, the 

 old female bags, within which are the eggs for this spring's 

 crop of caterpillars. 



Immediately upon the hatching of these eggs the young 

 caterpillar makes its way to the nearest leaf, where it begins 

 to feed and construct a bag for itself. This bag consists of 

 small fragments of leaves and bits of twigs held together by a 

 large amount of silk spun by the caterpillar. The construc- 

 tion of this bag by the young larva is extremely interesting 

 and well worth observing. Because of the soft body of the 

 larva, the protective bag is needed throughout its existence, 

 and as the caterpillar grows the case is constantly enlarged. 

 About the end of August the caterpillar completes its growth
