330 LEPIDOPTEEA. 



the aquatic habits of the larvae, which remind us of the Caddis 

 worms. Cataclysta is at once known by its slender body and 

 narrow wings, the hinder pair of which have a row of eye-like 

 spots along the hind margin. The larva is elongate, with a pale 

 head, and is aquatic, feeding beneath the leaves of the Duck 

 weed, living in a cylindrical silken case covered with leaves. 

 The pupa has a long ventral projection, and is enclosed in the 

 case of the larva. C. fulicalis Clemens has, on the outer mar- 

 gin of the hind wings, a row of five black lunules connected 

 by intermediate metallic violet blue spots, and behind them a 

 row of orange yellow dots. 



The larva of Paraponyx is provided with branchiae and spira- 

 cles ; the pupa residing in a cocoon among leaves under water. 

 Hydrocampa has large white spots on the outer edge of the 

 fore wings. The larva is rather thick, attenuated at each end, 

 with a black head. It is aquatic, living in a flat case under 

 the leaves of water lilies. The pupa resem- 

 bles that of Cataclysta. 



The genus Botys (Fig. 253) includes 

 many species, in which the conical abdomen 

 is longer than the wings, and the tip of 

 Fig. 253. the front pair is often prolonged. The larva 



is said by Stainton to be lively, attenuated at each end and 

 semitransparent, with warty spots. It feeds in rolled up 

 leaves. The pupa is elongate, smooth, enclosed in a slight co- 

 coon among leaves. B. verticalis Albin is whitish, with the 

 outer edge of the fore wings dark grayish. The larva feeds on 

 the nettle. B. citrina G. and R. is a bright yellow species. 



The genus Desmia is at once known by its resemblance to 

 Botys, and by its black body and wings, spotted with broad 

 white patches, while the male antennae are swollen in the middle. 

 D. maculalis Westwood, the Grape leaf folder, is shiny black, 

 with a white fringe on its wings, which are spotted in the mid- 

 dle with white patches, and with two white bands on the abdo- 

 men of the female. It is found chiefly in the Southern States, 

 where it attacks the grape. The larva, according to Riley, who 

 observed the moth in Southern Illinois, is "glass-green, and 

 folds a leaf, or attaches two, that may be close together, by aid 

 of a few silken threads. It is very active, jumping and jerk-
