Summary

Eburia quadrigeminata, commonly known as the ivory-marked beetle, is a wood-boring beetle found primarily in North America that can emerge from wood decades after larval development begins.

Physical Characteristics

Adults measure 12–25 mm (0.47–0.98 in) in length; larvae bore in heartwood of hardwoods.

Habitat

Deciduous forests.

Distribution

United States (Texas, Florida, New York, Minnesota); introduced in Cuba and Argentina.

Diet

Adults may feed on rotting fruit and nectar; larvae feed on a wide variety of hardwoods including oak, ash, hickory, locust, chestnut, maple, elm, beech, and cherry.

Life Cycle

Delayed emergence; adults can emerge after 10-40 years, as noted by historical observations.

Economic Impact

Known for emerging from furniture after many years, with a noted case of emergence from a 40-year-old birch bookcase.

Collecting Methods

  • Attracted to light traps
  • Bait traps

Misconceptions
