斑衣蜡蝉：美国东北的入侵物种

最近，美国东北出现了很多斑衣蜡蝉。它们第一次进入美国是在2012年。

自从2012年以来，它们真快传播了。因为斑衣蜡蝉是入侵物种，美国的本土树木没有足够的防御物能力，因此很多本土树木枯死了。斑衣蜡蝉还伤害了农作物。

去年在宾夕法尼亚，我没看到斑衣蜡蝉，但今年到处都有了。

Spotted lantern flies: The invasive species in the American Northeast

Recently, many spotted lantern flies have appeared in the American Northwest. They first came to America in 2012.

Since 2012, they have rapidly spread. Since spotted lantern flies are an invasive species, native trees in America are not able to defend themselves against them and are dying. Spotted lantern flies are also destroying crops.

Last year, I did not see any spotted lantern flies in Pennsylvania, but this year they are everywhere.
