on the under side of the purslane leaf, either singly or in clusters 
of from two to five. The larva hatches in two or three days, and 
is at first light green or yellowish 
green with darker shading across 
the middle of the body. In eight 
or nine days it attains full growth 
after having passed through four 
molts. The full grown larva is 
light gray or dull white with black 
dashes on the sides of each seg¬ 
ment, and with the shadings of 
salmon pink.” 
“The full-grown larvae enter 
the ground for pupation, excavat¬ 
ing a tubular burrow in the sur¬ 
face soil, gumming the lining 
and closing the opening with a 
thin layer of particles of soil. . . . The insect remains in 
this state in the neighborhood of twelve days.” 
In the accompanying figures we show the egg, the pupa, 
and the adult larva and moth 
at certain times in Nebraska, 
Kansas, and the southwestern 
States generally, and ranges into 
northern Mexico. It appears 
to feed exclusively upon purs¬ 
lane, and as this plant is of no 
particular economic value, but 
is justly accounted as a trouble¬ 
some weed, we may wish bless¬ 
ings upon Copidryas gloveri.
