Revelation 9:3, 5, 10

Then out of the smoke locusts came upon the earth. And to them was given power, as the scorpions of the earth have power.

And they were not given authority to kill them, but to torment them for five months. Their torment was like the torment of a scorpion when it strikes a man.

They had tails like scorpions, and there were stings in their tails. Their power was to hurt men five months.
