CHAPTER V. 
THE LEPIDOPTERA WITH WINGS UNITED BY A HOOK. 
( Chalinoptera .) 
All these Lepidoptera were formerly called moths or crepuscular 
and nocturnal flyers, but as some of the night-loving tribes were 
equally active during sunshine, and as none of them really 
wandered in the depths of the darkness, when everything sleeps, 
there was no wisdom in keeping up these popular distinctions. 
The structure which retains the hind and fore wings on each 
side together is a very good distinction, especially as it is 
common to most twilight and nocturnal Lepidoptera , it being 
deficient in the butterflies ; nevertheless, it is wanting in some 
kinds of moths. 
The tints of the wings of moths (under this term we include 
the nocturnal and crepuscular Chalinoptera) are principally shades 
of grey and brown, and resemble the colours of the trees and 
walls, when the light is dim, and night is advancing. But the 
wings of some, although not so brilliant and coruscating as those 
of the butterflies, are exquisitely delicate and soft in their tone. 
Some of the moths that fly by day, and thus lead the life of 
butterflies, often have colours as glowing as these have, but the 
tints are never brilliant and sparkling. The educated eye can 
distinguish at once between the scales of a butterfly and those 
of the brightest of moths. 
The wings of moths rest upon the body of the insect when 
in repose, and are not stuck upright like those of the butterflies. 
The antennae of the moths are very different in shape to 
those of the butterflies, as can readily be seen by comparing
