    Ivory Marked Beetle - (Eburia quadrigeminata)

    The Ivory Marked Beetle is a late bloomer. Its larvae bore deep into trees, possibly emerging years later from furniture.

    Staff Writer (7/14/2017): The defining ivory spots on the top of this beetle come in pairs. They are usually found in forests or lumberyards. Adults eat leaves and twigs. They are most active in the summer and can be seen flying around. Females lay one egg at a time in fissures or cracks in tree bark. Larval development can take years.

    After hatching, larvae bore deep into tough, central heartwood of a tree, consequently destroying it from the inside. Trees such as oak, maple, hickory and ash are popular sites for larval infestation.

    Because they can compromise the integrity of the wood as they tunnel through it, Ivory Marked Beetles may become a nuisance to the lumber industry. Some of the wood the larvae enter is still usable and since their presence may not be detected during construction, adult beetles can emerge from finished woodwork years after it was built or installed. Sometimes the wood they bore into is destined to become firewood so adults have been seen inside homes by customers who bought the seasoned wood fuel.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
