California Marble
Euchloe hyantis (W.H. Edwards, 1871)
Family: Pieridae
Subfamily: Pierinae
Identification: Upperside of forewing with narrow cell bar very close to edge of wing. Cell bar usually devoid of white scales. Underside cream-white; hindwing with yellow-green to green marbling.
Wing Span: 1 - 1 1/4 inches (2.8-3.7 cm).
Life History: Males patrol near host plants or on hilltops for receptive females. Eggs are laid singly under host plant leaves; flowers and fruits are the preferred food of the caterpillars. Chrysalids hibernate.
Flight: One flight from April- early July.
Caterpillar Hosts: Plants in the mustard (Brassicaceae) family, especially Jewel-flower (Streptanthus) species.
Adult Food: Flower nectar including that of hosts and others such as tansy-mustard or pussy-paws.
Habitat: Rocky canyons, cliffs, moraines, gravelly flats.
Range: Southern Oregon south through California west of Sierra Nevada crest to northern Baja California.
Conservation:
NCGR: Euchloe hyantis andrewsi has The Nature Conservancy Global Rank of T1 - Critically imperiled globally because of extreme rarity (5 or fewer occurrences, or very few remaining individuals). Development and threat from invasive alien weeds are also of concern.
Management Needs: Manage habitat with host plants.

Pollinator Week was June 20-26, 2022!
Butterflies and moths are accidental pollinators of many flowering plants. While most species do not have special structures to carry pollen, they do brush against pollen and transfer it to other flowers.
Did you know? The Eastern Tailed-Blue (Cupido comyntas) flies close to the ground and uses its short proboscis to probe flowers of wild strawberry, white sweet clover, and other low-lying plants.
