LEPIDOPTERA. LARV.E. 289 



emulating the gallery-makers of the Pyralidinae, which 

 live in hives, constructs similar silken passages in the 

 nests of Ants. 



Many genera feed like those of other groups, naked, 

 and on the exposed surface of leaves, or snugly sheltered 

 within leaves which are rolled up. 



The two last families, containing the Plume Moths, 

 differ from each other in both larvae and pupae. The 

 ten-plume Moths, Pterophorina, have hairy larvae and 

 naked pupae, which, fastened by the tail, are, at least in 

 one species, remarkable for activity and irritability, 

 suddenly reversing their position if disturbed, and as 

 suddenly returning to their former position, head up- 

 wards, after a few moments. 



The larvae of the twenty-plumes, Alucitina, are 

 hairless, and the pupa3 enclosed in cocoons.
