THE BUTTERFLY 4I 



On each side of the proboscis find a feathery labial palpus. 

 Note the eyes. Do you find simple eyes? How many 

 pairs of legs? For what are they used? Does the butter- 

 fly walk? 



(3) Note the wings. How many? Where attached? 

 For what are they used ? Do you find a backward extension 

 of the mesothorax consisting of two parts ? These are the 

 patagia or wing lappers. 



How many segments in the abdomen ? 



(4) Make the following drawings : 



(a) Drawing of left side with wings folded (X2). 



(b) Drawing of dorsal side with wings expanded (X2). 



(c) Scrape powder off of wing and draw (high power). 



(d) Scrape down off of body and draw (high power). 

 Wings of the Butterfly. — (i) Get a specimen of the 



Anosia plexippus* and remove the wings. Note the differ- 

 ences in shape between the outer and inner wings. Do you 

 find any peculiar markings on them ? The stripes indicate 

 the position of the veins. How are they arranged? Do 

 they look like those of the grasshopper ? 



(2) The front margin of the wing is the costal margin ; 

 the one farther from the body is the outer margin, and the 

 one below is the hind margin. The first front vein is the 

 costal, the second is the sub-costal, the third is the radius. 

 Under this in the part near the body is a large cell without 

 veins, called the disk. On the outside of this cell runs the 

 media divided into three divisions. Below the cell is the 

 cubitus which is also subdivided. The last vein is the anal 

 vein. 



*Note; This is the large brown butterfly with black veins on the 

 wings. It is common everywhere.
