Australian Tortoise Beetle

Trachymela sloanei

Also 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.

Responsible observation
  • Examine bark crevices: Gently check peeling Eucalyptus bark during the day where adults shelter.
  • Spot leaf damage: Look for distinct scalloped notches carved out along fresh leaf margins.
  • Night searching: Use a flashlight after dark to spot beetles actively grazing on outer canopy foliage.
