Habits. — Food-plants : Pisonia morindifolia R. Br. and 

 P. aculeata Linn., family Nyctaginacese. These shrubs, both 

 known locally as the " lettuce tree," owing to the leaves 

 resembling those of the lettuce, are grown in gardens in Bombay, 

 Belgaum and other places, where the larva? have been found. 

 In the last instar the larva rests on. the stem and hidden among 

 the leaves. In the resting position the horn is held horizontally, 

 but when the larva is moving it is bent forwards over the dorsum 

 at each forward movement of the claspers. The moth has 

 been caught at flowers after dark, but does not appear to be 

 attracted by light.
