It may be small, but the Spotted Peppergrass Moth is bright in its own way. Shiny white wings are literally peppered with medium-sized black dots. The bottom of each wing has longer black marks that appear as trios thanks to interruptions by white veins. The face is black as are the labial palps in front, which look like a black ‘nose’ or ‘snout’. Eyes are large and black, bulging out of the side of the head.
Caterpillars feed on peppergrass, a native plant in the mustard family that is grows in many places, but especially in weedy areas. Like dandelions, this plant is often considered a weed in lawns despite being edible. Field pennycress and cabbage are also food plants to caterpillars. Adults begin flying when the weather warms in spring, and they remain active through the summer. Like many moths, they are attracted to lights at night. Look for them in gardens growing cabbage, and in weedy areas and lots where peppergrasses grow.

Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used for sensing.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
