Quick Summary

The Malayan leaf beetle, also known as the fiddle beetle (Mormolyce), is a unique insect belonging to the ground beetle family (Carabidae). It measures approximately 100 mm (4 inches) long and is characterized by its violin-like shape, with a slender head and thorax and wide wing covers (elytra). This flat beetle uses its elongated head to search for prey in crevices, under tree bark, and within porous fungi. While most leaf beetles are known for feeding on plants, the Malayan leaf beetle is carnivorous, preying on other insects.12
