Eumegistus illustris is a beetle from the fungus beetle family. It has bright coloration and lives in tropical forests.
Eumegistus illustris is distinguished by a bright pattern on its elytra. It is important for the forest because it accelerates the decomposition of fungi and the return of nutrients to the soil.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
