Where it lives

Typical habitats: gardens
old fields
roadsides
dunes
Range: It migrates north from northern Mexico and the southwestern United States, temporarily colonizing much of the United States and Canada. Numbers vary greatly from year to year.
Preferred conditions: Open, sunny, and disturbed places with nectar flowers and low are especially suitable.
Migration: Adults move north from northern Mexico and the Southwest, and large flights can follow wet desert winters.

Behavior

Diet: Adults drink nectar from many flowers, especially thistles, asters, cosmos, blazing star, and other tall daisy-family flowers.
Activity: Males perch or patrol open ground and hilltops in the afternoon while looking for females.
Overwintering: Adults survive winter mainly in the South and during mild winters, so northern areas are recolonized by migrants.

Life cycle

Larva: Females place eggs singly on leaves. Caterpillars tie leaves together with silk and feed inside the shelter.
Caterpillar food plants: Caterpillars use more than 100 host plants, with thistles, mallows, hollyhocks, and legumes among the favorites.

About the name: Older references may use Cynthia cardui for this butterfly.
