White, 1855

Dere thoracica is a longhorn () first reported in the United States in 2021. The was previously known from East Asia (China, Japan, Korea) before its in the eastern United States, where it has since undergone range expansion. As a cerambycid beetle, it belongs to a whose are predominantly wood-borers, though specific biological details for this species remain limited in published literature.

Distribution

to East Asia, with records from China, Japan, and Korea. First detected in the United States in the eastern region, where it has subsequently expanded its range. The ' establishment in North America represents a recent range extension.

Human Relevance

The of D. thoracica in the United States has prompted efforts to track its range expansion and potential impacts. As a non- , its wood-boring biology raises questions about possible effects on native and cultivated , though specific pest status has not been established.

Similar Taxa

Other Dere species share the tribe Cleomenini and require careful morphological examination to distinguish; D. thoracica's thoracic patterning and elytral differ from related .
Native U.S. CerambycinaeMay be mistaken for other longhorn in general appearance, but Dere thoracica's specific combination of antennal length, body proportions, and coloration allows separation from most fauna.

Detection History

The first U.S. report of D. thoracica was published in 2021 in The , documenting the ' arrival and providing initial notes on recognition and biology. A subsequent 2024 publication in the same journal updated information on use, methods, and distribution in the eastern United States, indicating active range expansion since initial detection.

Research Gaps

Despite two recent publications, detailed biological information—including larval plants, complete , and ecological impacts in the range—remains incompletely documented for this .
