18 BUTTERFLIES. 
under surface of the wings is also ornamented in a similar 
way, but is fainter, and especially that of the lower wings 
resembles the bark of trees. Faintly marked upon them are 
the figures 98 89. 
This beautiful insect feeds as a caterpillar upon the net- 
tle and hop, but in the winged state it is a great admirer of 
fallen and overripe fruit. It is attracted in large numbers to 
fallen apples or pears, and is not slow to absorb their sweet 
sap withits tongue. Other butterflies are also attracted, 
as well as ants, flies, and wasps as shown in the illustration 
(Fig. 18), and even snails are fond of it. 
THE URSULA OR SOVEREIGN. 
(Limenitis ursula Fab.). 
During the months of June and July we mav see a most 
beautiful butterfly flying about cherry and plum trees, evi- 
dently in the act of depositing eggs. This medium-sized 
and handsome insect is of a sombre bluish-black or blackish- 
brown color, having the wings bordered with blue; the 
under-wings possess marginal rows of bluish crescents of 
varying size; the inner row in the female is less marked, and 
each crescent is supported behind by a deep orange patch or 
point. Several white spots occur near the tips on the upper 
surface of the fore-wings. All the margins of the wings are 
slightly crenate, the hollows being edged with white. The 
under side of the wings, which measure about three inches 
across, contain a number of large brownish spots. The 
females deposit eggs upon the leaves of the wild and culti- 
vated cherries, plums, and occasionally of the apple. The 
mature caterpillars are about an inch and a quarter long, of 
an olive-green color, variegated with white, russet, reddish- 
yellow and ochreous. They possess two long reddish horns 
behind their heads, and two green tubercles on each of the 
other segments, with the exception of those on the fifth,
