Dogbane Leaf Beetle (Family Chrysomelidae)
Dogbane Leaf Beetles are oval-ish, mostly measure less than a half an inch, come in bright colors, have un-spectacular antennae, smallish heads often shielded by a large-ish prothorax (first segment of the thorax), short legs, and domed elytra. The DLB’s incandescence is the result of the play of light on exceedingly small, tilted plates that overlay its pigment layer. Light bounces off both the pigment and the plates, and the colors change with the angle of the observer.
