This Order is divided into Butterflies and Moths ; the 

 Butterflies are distinguishable by their horns being almost 

 invariably thin and long, ending in a knob (see fig. p. 389) ; also 

 by their light and elegant shape, and beautiful colouring. They 

 mostly fly by day, and when at rest carry their wings erect. 



Lobster Moth {Stattroims fagi), male. 



The Moths are distinguishable by the horns nei-er beiu'T 

 club-shaped, but generally thread-like or with side branches ; 

 and they commonly rest with their wings expanded, and are 

 of a heavier make and more sluggish in flight than the 

 Butterflies ; also, though not exclusively evening or night-fliers, 

 many of them are so. 



The family of the Clearwing Moths (Sesiidce) is very 

 peculiar, and difters from the other Lepidoptera in the wings 

 being more or less transparent or "dear," and without 

 " scales " ; but from other characteristics resembling those of 

 this Order it has been placed in it. 



Cui-rant Cleai'wing (Scsia tiindiformis). 



The larvre of the Clearwings feed and change to chrysalids 

 in branches or roots of trees.

 Moths, see those of Cabbage, Turnip, Apple, &c.
