4 BUTTERFLIES OF MAINE. 
CLASSIFICATION. 
Insects have been divided by naturalists into the following 
orders : 
HyMENOPTERA, which include the bees, wasps, ants, ichneu- 
mon flies, sawflies, ete. 
LeprmpoprERaA, which include the butterflies and moths. 
DiptTerRA, which include the true flies. 
CoLEOPTERA, or beetles. 
HemIPTERA, or the true bugs. 
OrtTHortTEeRA, which include the crickets, grasshoppers, lo- 
custs etc. 
NEvUROPTERA, Which include the dragon flies, darning needles 
etc. 
The LermortTera are characterized by having four ample 
wings covered on both sides with minute overlapping scales 
which are easily rubbed otf, and appear like a fine powder. 
They are naturally divided into the butterflies (J?thopalocera) 
and moths (ffeterocera). " 
The butterflies have two thread-like antenne, or feelers, on 
the head, each of which is enlarged, at the outer end, into a 
knob or club. They fly in the day time, and keep their 
wings elevated when at rest, at least the fore wings. 
The moths have the antennz variable in form, but never 
enlarged at the outer end. They fly mostly by night, and 
when they alight they spread their wings out more or less 
horizontally, or close them around their bodies. 
TRANSFORMATIONS. 
There are four distinct periods in the existence of butter- 
flies: The EGG, the LARVA, the PUPA or CHRYSALIS and the 
IMAGO Or PERFECT INSECT. 
The eggs of butterflies are more or less globular, conoid 
or spindle shaped, with their surfaces smooth, or marked 
with a variety of regular sculpture in the different species, 
and of different colors, among which, white, green and
