I’ve put out fermented bait (rotten fruit, etc.) to attract butterflies and moths. However, for the last three nights I’ve been surprised to find an ivory-marked beetle (Eburia quadrigeminata) that has come to feed. This is the first one I’ve ever seen and I think it’s quite handsome. It apparently doesn’t bite, although I didn’t test it.
The larvae burrow into and feed on dead wood. They normally stay in the wood for 2 years. However, they can emerge from furniture or hardwood flooring after 25 or more years. I’m glad to add this beetle to our list of backyard insects.
