Keep your eyes open for the Asian longhorned beetle | Michigan Radio Yeah searching for feather horned beetle too, pretty sure not: Meet the Feather-horned Beetle with Huge, Bushy 'Eyebrows'! | Featured Creature The bushy feelers are different, and my bug has back markings kinda like a watermelon, not speckles.
