142 THE GREAT TIGEK MOTH. 



segments are provided with three elevated, bluisli 

 warts ; these are situated on the sides. It feeds on 

 lettuces, chickweek, and nettles ; and when appre- 

 hensive of danger, rolls itself up like a hedgehog. 

 It changes into the cluysalis state in May ; and the 

 latter end of June, or the beginning of July, is 

 transfoimed into the perfect moth. The pupa is 

 l)lack, or brown, and enclosed in a case, or follicle. 

 This moth is to be found abundantly in most 

 places of Great Britain, and may be seen flitting 

 about, where nettles are growing, in the dusk. It 

 makes its appearance about the end of July.
