180 Bugs, Butterflies, and Beetles 



ing willows, which with great trouble and some 

 little expense I procured and set out along the 

 edge of Big Tink Pond, Pike County, Pennsyl- 

 vania, were completely stripped of their leaves by 

 the larvse of this imported butterfly. 



The greed}^ babies are black, lively caterpillars 

 and they live together in numerous communities, 

 the first brood coming early in June — that's the 

 time they began on my willow trees, and two 

 seasons' diligent work by these caterpillars killed 

 every tree I had. They have black heads, with 

 spines sticking up from them. They have six or 

 seven of these jagged spines on each division of 

 the body. When full-grown they are an inch and 

 three-quarters long, and they do not look at all 

 pretty; in fact in olden times they were supposed 

 to be very poisonous and able to give you danger- 

 ous woimds and they certainl}^ look like villains. 

 At one time, people cut down all the poplar trees 

 around their dweUings because they were afraid 

 of the Antiopa caterpillars, which feed upon the 

 poplar as well as the willow. Fig. 158 shows the 

 caterpillar. Fig. 159 shows the chrysalis and Fig, 

 160 the butterfly.
