Balsam woolly adelgid

Balsam woolly adelgids (Adelges piceae) are small wingless insects that infest and kill firs, especially balsam fir and Fraser fir. They are an invasive species from Europe introduced to the United States around 1900. Because this species is not native to the United States, the Fraser fir has not evolved any type of defense against it.
