Revelation 9:7-11

7The locusts resembled horses prepared and equipped for battle; and on their heads appeared to be [something like] golden crowns, and their faces resembled human faces.

8They had hair like the hair of women, and their teeth were like the teeth of lions.

9They had breastplates (scales) like breastplates made of iron; and the [whirring] noise of their wings was like the [thunderous] noise of countless horse-drawn chariots charging [at full speed] into battle.

10They have tails like scorpions, and stingers; and in their tails is their power to hurt people for five months.

11They have as king over them, the angel of the abyss (the bottomless pit); in Hebrew his name is Abaddon (destruction), and in Greek he is called Apollyon (destroyer-king).
