Whites and Yellows
Scientific Name:
Pieridae
Brief Description: Whites and yellows belong to the butterfly family Pieridae, which includes about 1,100 species worldwide. They are small to medium-sized, strong fliers recognized by white, yellow, or orange wings often marked with black spots or dark tips. Their unique colors come from waste pigments stored in their scales.
Physical Characteristics:
Size: Small to medium, with wingspans typically ranging from 1.25 to 3 inches.
Coloration: Dominated by whites, pale creams, and shades of lemon yellow to intense orange. Most species feature black or charcoal-colored borders or spots on the upper wing surfaces.
Markings: Frequently feature dark charcoal tips on the forewings and black dots (often varying between males and females). Undersides are often pale green or yellowish for camouflage.
Legs: Both sexes possess six fully functional, walking legs (unlike some other butterfly families with reduced front legs).
Ultraviolet Patterns: Many species possess complex, hidden ultraviolet wing patterns invisible to humans. Females use these UV reflections to signal to courting males during flight.
Habitat and Distribution:
Locations: Found globally, heavily represented in open fields, meadows, gardens, and road edges.
Behavior: Highly active during warm daylight hours, frequently seen nectaring on flowers or engaging in "mud-puddling" on damp soil.
Migration: While many "whites" overwinter locally as pupae, several "yellow" or sulfur species migrate northward each spring from warmer southern regions.
