Larvae of the Ivory Marked Beetle bore deep into trees, possibly emerging years later from furniture made in the interim.
The defining ivory dashes on the top of this beetle come in pairs. They are usually found in forests or lumberyards where the orange-brown adults eat leaves and twigs. They are small and most active in the summer when they are seen flying around on hot days.
Females lay one egg at a time in fissures or cracks in tree bark. Larval development can take years. After hatching, they bore deep into tough, central heartwood of a tree, destroying it from the inside. Trees such as oak, maple, hickory and ash are popular hosts 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.
Sometimes wood gets harvested, and the small grubs escape detection and find themselves part of a table, floor, or sofa frame. 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 found inside homes by customers who buy seasoned wood fuel.
Scientific Name: Eburia quadrigeminata
Size (Adult; Length): 13mm to 25mm (0.51in to 0.98in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
