FEEDING LIZARDS WITH COLORED INSECTS. 273 



very difficult to detect when at rest. It is in the habit of remain- 

 ing motionless for a long while. The specimen introduced was 

 at once eaten. 



Papilio cresphontes Cramer. One specimen was introduced 

 April 23 and four lizards at once seized the outspread wings. 

 They showed no preference for the body but ate the wings first, 

 as is usually the case. On May 7 the wings of the specimen 

 introduced were almost entirely eaten when the lizard happened 

 to drop it. It remained quiet, and the lizard would only take it 

 again after I had made the butterfly move several times. 1 



DeilepJiila lincata. May 5. Two of these Sphingid moths 

 were introduced and seized at once. They fluttered continuously 

 and thus frustrated the attempts of several other lizards that 

 were trying to participate. One moth was held by the head, 

 the other by the wing for quite a while, till they ceased fluttering, 

 and were then eaten. 



Species unknown. May 4. This small moth is of black and 

 orange, the typical warning coloration. It was eaten at once 

 without any symptoms of dislike being shown.

Lygceid. May 5. Just after the above-mentioned moth was 

 eaten four of these bugs were introduced. They are of the typi- 

 cal black-and-red or orange warning colors and have a very dis- 

 agreeable odor. The same lizard that ate the moth at once 

 seized a bug, chewed it a moment and spit it out, then licked his 

 mouth for some time as if to remove the bad taste. Another 

 lizard examined a second bug but made no attempt to take it. 

 One bug was eaten later by the third lizard and the other two 

 were gone next morning. May 13 a bug was introduced, seized 

 at once and then rejected as before. It is evidently quite un- 

 palatable. 



BracJiymena my ops. Three were introduced November 8, but 

 were never noticed by the lizards. The bug is gray in color, 



1 A glass jar containing live butterflies was placed on a chair about two and one 

 half or three feet from the cage of Sceloporus. A large male lizard immediately 

 climbed up the side of the cage, eyed the butterflies eagerly and seemed quite excited. 

 This happened a few days later with several of the lizards. When the insects were 

 introduced they were seized and eaten at once, several lizards quarreling over a de- 

 sirable specimen and sharing it among themselves.
