Chrysomela scripta
The Cottonwood Leaf Beetle is a small, shiny beetle that loves to munch on cottonwood leaves. They are bright yellow with black spots, making them easy to spot on the trees they eat.
Habitat: Forests
The Cottonwood Leaf Beetle has an oval, somewhat flattened body. It features a shiny, often metallic black head and thorax, with distinctive yellow or orange stripes running down its black wing covers, sometimes dotted with black spots. Its bright coloration makes it visually distinct from many other leaf beetles.
