The Old World woodwasp (Sirex noctilio Fabricius) has been found in New York, the first wild occurrence the U.S., according to this report at ABC News. This wasp species has already caused great harm to pine forests in other parts of the world, so the government is none too happy about the discovery. Old World wasps kill trees in part by spreading toxic fungal spores (Amylostereum areolatum) whereever the females lay their eggs. Bonus points to the AP for using the wasp's scientific name (with Author!) in the article.
