Brown beetle, four white spots
July 20, 2009
I found this little fella flying clumsily around my room tonight and caught him in my handy dandy bug catcher (after he made a mad dash for my hair! yikes!) and I was wondering what he is. He’s 3/4″ in length, caramel brown, with four white spots on his back (technically 8, i think, but they’re in groups of 2).
Your beetle is an Ivory Marked Beetle, Eburia quadrigeminata, one of the Long Horned Borer Beetles in the family Cerambycidae. According to BugGuide: “Larvae bore into heartwood of deciduous trees, esp. ash, hickory. May emerge from finished lumber years after milling.”
