Eburia quadrigeminata

Also known as Ivory-marked Borer, Four-spotted Ivory Beetle

Ivory-marked beetles are striking longhorn beetles recognized by four pairs of raised, pale yellow spots resembling polished ivory on their elongate light-brown elytra. Their larvae bore deep into the heartwood of oaks, hickories, and maples, sometimes remaining inside cured timber or furniture for decades before emerging as adults. Active mainly on warm summer nights, adults are attracted to artificial lights and readily feed on sap flows on tree trunks.
