THE BROWN-TAIL MOTH 



dominal segments are a distinct white color, forming a band 

 of white dashes along either side of the caterpillar, which 

 is so characteristic of it.. The third molt occurs during the 

 last week of May (May 28-30, 1905), this usually being the 

 last molt before pupation, but sometimes, as described by 

 Fernald and Kirldand, a fourth molt occurs, thus making 

 five stages of the caterpillar in the spring. The caterpillars 

 are now usually full grown (Fig. 11), and from an inch 

 to an inch and a quarter long. The head is pale brown.
