Interpretive Summary: Woodwasps can cause millions of dollars of damage each year by causing mortality to trees or reducing the quality of lumber. Adults may also be an annoyance when emerging from wood used in construction in buildings or from firewood in homes. Eriotremix formosanus, a woodwasp native to southeastern Asia, was first discovered in the United States in 1974 in Florida and Georgia. It is now found in nine states from Virginia to Texas. Records indicate that its host preferences are oak and hickory. The current distribution and known information on the hosts and habits of the woodwasp are presented. Knowledge of its current status in the United States will help federal, state, and local agencies determine necessary control or quarantine measures.
