64 DIFFERENCE OF THE ANTENN.E. 
Lucy, You said, that moths fly after 
sunset, butterflies in the day-time, and 
the sphinx only at sunrise and sunset; 
is there no other difference? If they 
were all to fly about in the day-time, 
how could 1 distinguish them ? 
Mother, Their general appearance, 
as well as their modes of flying, are very 
different ; and, on close examination, 
you will find, that their antennas also 
vary. 
Lucy. I think, you said, antennae 
were horns r 
Mother, Yes ; they are somewhat 
like horns, and they are also called 
feelers, because insects seem to be very 
careful in feeling their way with them. 
Here are drawings of three kinds of an- 
tennae : this one 
is called clavated* , or club shaped; and 
all butterflies invariably have antennae of 
this form. 
* From Clava, a club.
