Laricobius osakensis is a species of Derodontid beetle native to Japan. Described in 2011, it feeds exclusively on hemlock woolly adelgid (Adelges tsugae), an invasive insect species that is destroying huge numbers of hemlock trees in eastern North America.{{Cite journal |title=Host Range of Laricobius osakensis (Coleoptera: Derodontidae), a New Biological Control Agent of Hemlock Woolly Adelgid (Hemiptera: Adelgidae) |journal=Environmental Entomology |volume=40 |issue=2 |pages=324 |year=2011 |last1=Vieira |first1=L.
