A STORY OF COMMON BUTTERFLIES 



Anusia plcxippits is supposed to be distasteful to birds and to advertise this fact by its "waniing" reddisli color. 

 Birds are supposed to like the taste of species of Basilanhia and the resemblance of arckippiis to phwippus is explained 

 on the ground that it "mimics" that species and the birds are deceived. The departure of archippus from the color of its 

 relatives is indicated by a comparison with arthemis. It is belie\ed that this mimicry has been brought about by natmal 

 selection, not by conscious intention of arckippiis. Anosia plexippus is the "monarch" or milkweed butterfly. The 

 latter name indicates the food of its larva, which is shown together with the pujia in its "green house with golden nails." 

 The other lar\-a and pupa belong to air/iippu^, and they show that the mimicry exists i>nly in the adult
