The Burrowing Bug (Cydnus aterrimus) is a completely harmless insect known for its shiny black, oval body and specialized diet. Measuring roughly 9 to 12 mm long, these bugs thrive in warm, sandy environments like coastal dunes, where they burrow into the soil to feed on plant roots.
Here are the key facts about this unique insect:
Diet & Host Plants: They specialize in feeding on the roots and sap of plants in the spurge family (genus Euphorbia). While adults mostly stay underground, they can occasionally be seen above ground hiding under leaves or copulating on flowers.
Defense Mechanism: When disturbed or handled, they emit a powerful, intensely foul-smelling odor. Additionally, they will often "play dead" to avoid predators.
