THE TUE There arc four tour stages In tho the life his history tory of ot a u the tile egg CbS the tho larva or caterpillar tho the pupa iua or and tho adult Thu eggs of or arc are very er beautiful usually marked ribbed or 01 covered with a u network of raised lines are generally largo lurge enough to bi Jl seen with tho the naked eye e e and uro are must most frequently mid lull Kingly on leaves or sterns stems They The are arc pale palo green greet and yellow yellowin ellow in III shads hadt of almost any color except red rC or black But Dut the tho eggs bo come dark when just jUll ready to tu hatch because beCu e the tho color of ot the tho caterpillars Mad bead shows through tho the shell heli On all om em the first thing many of tho tIm larva do o is to eat cat up tho the egg case FOOD OK Ol 0 THE TI Tho The head hend of or the tho butterfly consists conist principally of or eyes a largo large compound pair pall one ono on each side of at the tho head TIm Tho proboscis

take tako no solid food toad Tho The butterfly uses umes this tube tuba as am ama n a suction pump by Iy which It 11 first ret lifts Its Us food tood to its mouth und then forces It on all to 10 the tho stomach Insects have havo sail vury glands and nna saliva salva to enable them to digest their food just as other oilier mini ani animals mals mais do Tho Tim caterpillar takes food Into Its mouth and passes pass it through an oesophagus Into a IL crop thence Into a II tube called tho the stomach thence into the small Intestine Into which tho the hepatic glands liver empty a IL diges digestive tive fluid thence into the tho colon into hito which empty the tho glands tho the kidneys during the process of at diges digos digestion lion tion Several of ot these processes can cnn bo be observed by b looking at tho the larva under undera a strong light lightHEART lightHEART lighthEART HEART AND NERVES NERVESA A long vessel vossel extends tho time length of the tho body bod right along tho the back This vessel usually dilated at the tho center Is called tho the heart hout or aorta It has valves pointing p forward and the tho blood Is III forced Into Inlo tho the heat head region by bythe b time the contraction of ot tho vessel Thence it Hows from tho the head to nil all parts of ot the tho body bOIl Tho The system Is IB on tho under or side of ot tho the body nI consists of a complex of
