Description: The
familiar Painted Lady is raised from caterpillar
to butterfly by thousands of school children
every year. Males and females have boldly
patterned black wings with bright orange
stripes and markings toward the body, and
white markings toward the ends of the wings.
The hindwing has a row of five black spots.
The body is brown. In North America, the
Painted Lady is often called the Cosmopolite
or the Thistle Butterfly. The Painted Lady
has a wingspan of about 8 centimeters (nearly
three inches).
Range:
The Painted Lady is found throughout the
world's temperate zones (and some tropical
zones), in every continent except Australia
and Antarctica. It may be the most widespread
butterfly in the world. They can be found
in virtually any habitats, but are especially
numerous in flowery mountain meadows. They
migrate from the south to the north in late
spring and may be present in most areas from
March to October. In desert climates, they
may persist year-round.
Life
Cycle: Female Painted Ladies lay
tiny pale-green eggs on thistle, mallow,
or hollyhock leaves. When the larva hatches
they immediately begin feeding for five
to ten days before pupating (forming chrysalis).
The larva (caterpillar) quickly grows and
turns a blackish color with long spines
on its body. During this time it progresses
through four instars (periods of time between
moltings). The larva will soon become less
active and hang upside down in a "J"
formation from a twig or branch, attached by
a silken string. A green chrysalis will form
around the caterpillar. In seven to ten days
metamorphosis will become complete and the
butterfly emerges. Upon its emergence, the
butterfly will remain still while blood pumps
to its newly formed wings. In a few hours,
it will gain the ability to fly. After emerging
from the chrysalis, the butterfly has a life
span of about two weeks, during which it will
feed on the nectar of several kinds of flowers
including cosmos, blazing star, ironweed, thistle
and clover before mating. Three or four generations
(flights) of Painted Ladies may be produced
in a single year.
