IvE^PIDOPTERA — BUTTERFLIES AND MOTHS. 



The Lepidoptera are among- the most common and 

 showy of insects. The}^ have four scale covered 

 wings and a long bill or sucking tube, which, when not 

 in use, is rolled up in a little coil beneath the head. In 

 their young or larval state they are caterpillars or 

 worms, and are often very destructive to plants. We 

 have many species, several of them large and showy. 



Family Papilio; hind wings generally extended in 

 tail-like appendages. 



Genus Papilio; Papilio asterias; black, double 

 row of yellow dots on back, and a band of yellow dots 

 across wings, seven blue spots on hind wings, and eye

 pushes out two orange-colored, horn-like organs, which i 

 give out a strong, unpleasant smell. The female

 tl^ree and a half to four inches. P. turnus, the Turnus 

 butterfly; yellow marked, an orange-red spot in hind 

 wings; breadth, four to five inches; larva upon 

 leaves of apple, wild cherry, etc., green above, with 

 rows of blue dots. Remains a chrysalis through 

 winter. P. cresphontes, B. with a triangular band of * 

 yellow; in shape resembles turrus.

 plants; are green and slightly downy.
