Are Insects With Ivory Markings Harmful?

Ivory-marked beetles, also known as Eburia quadrigeminata, are a longhorn beetle that can cause significant damage to deciduous trees like oak, hickory, maple, cherry, ash, and elm. These beetles are not known to be poisonous, so their bites are unlikely to cause serious harm. However, they can cause mild irritation or allergic reactions in some individuals.

Ivory-marked beetles affect over 10 million species of animals without backbones, including earthworms, slugs, snails, and other arthropods. Alive animals, such as crayfish and shrimp, can also be indirectly affected by the presence of the beetle, as they can influence the health of the surrounding ecosystem. Adult Ivory-Marked Beetles seek out leaves and twigs for food, while larvae bore into the heartwood of trees. In certain areas, these beetle larvae can cause great damage to timber.

The larvae of ivory-marked beetles can cause mild to severe damage by boring into the stems of plants, interrupting water and nutrient flow. Infestations lead to weakened structures and potentially plant death if populations are high. In large numbers, these beetles could become serious pests to trees and cause significant damage. Mature trees with scars or “catfaces” which give larvae access to hardwood are often badly damaged. Adults may also attack lumber undergoing seasoning.

On the other hand, Ivory-marked borers do not attack living hardwoods but rather infest dead hardwood trees like hickory, locust, and ash. They apparently infest dead hardwood trees because they can compromise the integrity of the wood as they tunnel through it. The Ivory-marked beetle is non-toxic and generally doesn’t pose a risk to human health, so there’s no need for excessive worry.

In summary, Ivory-marked beetles can cause significant damage to deciduous trees, but their non-toxic nature and ability to bore into wood make them a nuisance to the lumber industry.
