This species has the same habits and life round as the preceding. 

 It is abundant in late summer, and feeds in colonies. Like the other, 



it jerks its head and tail into the air 

 when alarmed. The body of the cat- 

 erpillar is spiny, and is marked with 

 fine, narrow stripes of black and yel- 

 low. A short distance back of the 

 head is a hump which is conspicu- 

 ously red.

Control is the same 

 as for the preceding 

 species. The two will 

 be found on orchard 

 foliage at about the same 

 time of year.
