found in hundreds in Turnchapel Quarries, Plymouth, at 

 Newton Ferrars, Hessenford, everywhere round here prob- 

 ably. I have found it more common near Ragwort though I 

 have made no special comparisons." 



Larvae of Cinnabar Moth (Callimorpha Jacobaea). 



Food Plant: Commonly, the Ragwort (Senecio Jacobaea). 



The larvae usually attack the lower leaves first and work

 striking colouring of the larvae make them conspicuous even 

 at a little distance.

 be contagious; and the policy of slaughter and compensation

 investigations. 



In 1906 Dr. J. G. Rutherford as Veterinary Director 

 General, reports Dr. W. H. Pethick's experiments on a 200 

 acre farm at Cloverville in Antigonish county. He also notes 

 that Dr. Gilruth of New Zealand devoted considerable atten- 

 tion to a peculiar hepatic cirrhosis known as the Winton Dis- 

 ease, from which horses as well as cattle and sheep suffered 

 due to the ingestion of Ragwort. In Cape Colony, South
