wings erect above the back when at rest. There are some 
moths that have 
clubbed antennae,and 
others that fly by day 
but no moth presents 
all three of the charac¬ 
teristics given above. 
It is more difficult 
to distinguish the but¬ 
terflies from the skip¬ 
pers ; yet this can be 
easily done. In but¬ 
terflies the club of 
the antenna is bluntly 
rounded at the tip 
instead of being fur¬ 
nished with a re¬ 
curved point as in 
most skippers; the 
abdomen is very slen¬ 
der ; and some of the 
branches of radius of

apex of the discal cell (Fig. 455). There are butterflies in 
which all of the branches of radius present arise from the 
discal cell; but this is due to the fact that two of the 
branches coalesce to the edge of the wing, as is shown by 
the fact that in these butterflies radius has less than five 
branches. 
This superfamily includes four families, which can be 
separated as follows:—
