INSECTS INJURIOUS TO THE ORANGE. 



Since many of the insects most injurious to the orange 

 attack alike the branches, the leaves, and the fruit of the tree, 

 and sometimes the trunk also, the grouping of the species, car- 

 ried out when treating of the enemies' of other fruits, will not be 

 attempted with those of the orange. The insects belonging to 

 each order will be brought together and treated consecutively, 

 beginning with the Lepidoptera, which includes butterflies and 

 moths. The remedies for scale-insects, as they apply alike to 

 all the different species, will be referred to towards the end 

 of this section. 



No. 239. The Cresphontes Butterfly. 



Papilio cresphontes Fabr. 



In the perfect state, this is a large and handsome butterfly, 

 which measures, when its wings are spread, from four to five 

 inches across. The wings are black above, with an irregular, 

 triangular band of broad yellow spots, covering a considera- 

 ble portion of their surface, as shown in Fig. 389. The hind 

 wings have two long, projecting points or tails, with an oval 

 yellow spot on each ; they are also notched, and have the 

 indentations marked with yellow. The under side is yellow- 

 ish, with dusky veins and markings, and a row of crescent- 

 shaped blue spots on the hind wings. The body is black 

 above, yellow at the sides and beneath. 



The eggs are globular, and are deposited singly on the 

 leaves. The young caterpillars are very much like the full- 

 grown ones in form and color, but the gray markings are 

 darker, and the white blotches not so large as in the mature 

 larva. When full grown, it is about two and a half inches 

 long, and very peculiarly marked. (See Fig. 390.) Above
