The Rove Beetle, known in Indonesia as the Tomcat Beetle, and nicknamed the Dragon Bug due to its potent effects, is called duang kon kradok in Thai, meaning ‘tilted-ass beetle’, a reference to its distinctive raised posterior.

This Asian species, scientifically known as Paederus fuscipes, produces haemolymph containing paederin—a potent toxin released when the beetle is crushed against the skin. This toxin can cause severe blistering and irritation.

VENOMOUS! This beetle has a higly potent toxin that contains paederin, which is released when the beetle comes into contact with the skin, causing severe blistering, a condition known as paederus dermatitis. Initial symptoms include skin reddening and a burning sensation, followed by painful irritation and itching. If left untreated, this can lead to extensive pustules and blistering within days. Contact with the eyes can result in blindness. Treatment: Wash the area thoroughly with soap and water to remove the toxin. Apply soothing agents or corticosteroid creams for inflammation. Seek medical attention if symptoms are severe or worsen.
