Revelation 9:1, 3, 5

Then the fifth angel blew his trumpet, and I saw a star fall from the sky to the earth. The star was given the key to the deep hole that leads to the bottomless pit.

Then locusts came down to the earth out of the smoke, and they were given the power to sting like scorpions.

These locusts were not given the power to kill anyone, but to cause pain to the people for five months. And the pain they felt was like the pain a scorpion gives when it stings someone.
