Revelation 9:3-5

3Then locusts came out of the smoke on to the earth, and power was given to them like the power that scorpions have on the earth.

4They were told not to harm the grass of the earth, or any green plant, or any tree, but only those people who do not have God’s seal on their foreheads.

5They were not permitted to kill them but were to torment them for five months; their torment is like the torment caused by a scorpion when it stings someone.
