BLUE BUTTERFLY 
uimong the most conspicuous of the smaller European 
butterfiies 
Butterflies are divided into several groups, the first 
of which includes the Brush-footed Butterflies, 
so called because the front pair of legs is converted 
into hairy paws, useless for walking, and only 
employed for toilet purposes. This is a very exten- 
sive group, including about half the butterflies 
known, and is divided into several smaller sections. 
The most interesting species among the Danaids 
is the Monarch, one of the largest and commonest 
butterflies found in North America. It is migratory 
in its habits, and has succeeded in acclimatising 
itself throughout the Pacific islands as far as Australia 
and New Zealand, as well as in the Canaries; and 
so many specimens have been taken recently in the 
south of England that it seems not unlikely to take 
up its residence there also. It is a tawny butter- 
fly, not unlike the one represented on the preceding 
page, but much larger, measuring about 5 inches 
across the wings. The caterpillar is yellow, with trans- 
verse black bands, and a pair of long, black slender 
filaments near each extremity of the body. The 
pupa is pale green,- with golden spots, and is 
suspended by the tail, as is the case with most of those of the Brush-footed Butterflies. 
The next group, the LONG-wiNGED Butterflies, includes a considerable number of species 
with long rounded wings, found in tropical and sub-tropical America. A species with black 
and transparent markings is shown on page 710, but many have wholly transparent wings, 
£xcept for a narrow black or brown border. 
Turning to more familiar insects, there are several kinds of large or moderate-sized tawny 
butterflies, marked ■ with black spots 
and lines, called Fritillaries. The 
caterpillars are spiny, and feed on violets 
and Other low-growing plants. The pho- 
tograph on page 710 shows- the DrAN.\ 
Fritillary, a large and handsome 
species, which is somewhat of a rarity in 
the Southern States of America ; it meas- 
ures 4 inches in expanse, and the sexes 
are very dissimilar. It is dark brown, 
with a broad orange border spotted with 
black in the male, and rows of more 
or less connected green or white spots 
in the female. 
The Angle-wtxged Butterflie.s 
include several of the best known 
and most brightly coloured species, 
such as the Red Admiral, a velvety 
black butterfly, with a transverse red 
band on the four wings, and several 
white spots between this and the 
tip, the hind wings having a red 
border, spotted with black and blue. 
It measures about 2.1 inches across
