A species of worm called jumping snake worms is invading US forests. The worms are originally from Asia, but scientists say that they probably came to the US about 100 years ago via imported plants. Jumping snake worms cause damage to the forest floor, which hurts native insects, lizards, and birds.

Although the worms entered the US about 100 years ago, they’ve started to spread much faster over the past 15 years. In addition to the South and Mid-Atlantic, the jumping snake worms are now in some parts of the Northeast, Upper Midwest, and West as well. Scientists say that climate change may be the cause. As winters become warmer, the worms are moving into areas that used to be too cold for them.

The Asian giant hornet, another foreign insect species, started to invade the US last year. The hornets are killing native honeybees and can be deadly for humans as well. In Japan, they kill around 30 to 40 people every year. To stop the hornets from spreading in the US, scientists have been hunting for their nests and destroying them.
