COLOR AND PATTERN IN ANIMALS

with great fidelity a short broken- 

 off branch or chip of bark. Nu- 

 merous other moths and caterpil- 

 lars resemble bark and habitually 

 rest on it. Catocala, Schizura, 

 and other genera furnish ex- 

 amples familiar to the moth col- 

 lector. 



There are numerous instances 

 of special protective resemblance 

 among spiders. Many spiders 

 that live habitually on tree 

 trunks resemble bits of bark or 

 small, irregular masses of lichen. 

 A whole family of spiders, which 

 live in flower cups lying in wait 

 for insects, are white and pink 

 and particolored, resembling the 

 markings of the special flowers 

 frequented by them. This is, of 

 course, a special resemblance not 

 so much for protection as for ag- 

 gression; the insects coming to 

 visit the flowers are unable to 

 distinguish the spiders and fall 

 an easy prey to them. 



Any field student of insects, 



by paying attention to the matter of special protective resem- 

 blance, cpn soon make up a striking list of examples. Some 

 of these may be more convincing to him than to persons see- 

 ing his specimens 

 in the collecting 

 boxes, and some 

 indeed will prob- 

 ably be ques- 

 tioned by closet 

 naturalists. But 

 nevertheless no 

 collector or field
