WARNING COLOURS 



169 



The caterpillar is extremely conspicaous, being of a 

 cream colour with orange and black markings. Al- 

 though it belongs to the group of well- 

 concealed ' stick- caterpillars ' {Geome- 

 trcE), of which several instances have 

 been considered in Chapter III., it makes 

 no attempt to hold itself in any of the 

 attitudes characteristic of its group 

 (compare fig. 43 with figs. 1, 2, 3, 4, 6, 

 8, and 9). All observers agree that 

 birds, lizards, frogs, and spiders either 

 refuse this species altogether, or exhibit 

 signs of the most intense disgust after 

 tasting it.
