Oncideres rhodosticta is a species of longhorn beetle found in South America. It is characterized by its elongated body, reaching up to 3 centimeters in length, and its reddish-brown coloration. The species is known for its distinctive red spots or stipples on its elytra, which are the hardened forewings. Oncideres rhodosticta primarily feeds on the bark of various tree species, using its strong mandibles to create tunnels for egg-laying and larval development.
