Found this interesting fellow on my car door after work…it was night and it is summertime here. It is about 1.5 inches long…not a small bug. It flew into my car before I could study it any longer, luckily I got a nice pic. Thanks for taking your time to check out this bug.
This Longhorned Borer Beetle is an Ivory Marked Beetle, Eburia quadrigeminata, and it is also called a Four-Marked Ash Borer according to BugGuide. BugGuide also notes: “hosts include a wide variety of hardwoods (oak, ash, hickory, locust, chestnut, maple, elm, beech, cherry); larvae bore in heartwood” and the remarkable “Notorious for emerging from furniture after as many as 10-40 yrs.” You do not need to worry about the beetles boring into finished wood, however, if larvae are present when wood is milled, the metamorphosis period is affected lengthening the time the beetle remains in the larval and or pupal stages.
