Cottonwood Leaf Beetle (Chrysomela scripta): The adults and larvae (pictured here) of this beetle like to feed on willows, poplars, and (as you might guess) cottonwoods. They can be found throughout the US, including Alaska, in areas where there host plants exist. The adults overwinter and emerge in early spring to begin feeding on the new leaf growth. Females will lay lemon-yellow colored eggs in clusters of between 15 to 75 eggs on the underside of leaves. Depending on the latitude, they can have from two to several generations a year.
