Australian Tortoise Beetle
Trachymela sloaneiAlso known as Small Eucalyptus Tortoise Beetle, Sloane's Eucalyptus Tortoise Beetle
Australian tortoise beetles blend seamlessly against rough Eucalyptus bark with their textured, reddish-brown bodies. During daylight hours, adults huddle in bark crevices or leaf litter beneath host trees, emerging after dusk to feast on tender young foliage. While native to Australia, these leaf beetles have established in several international regions alongside Eucalyptus plantings.
