9:8 And they had hair like the hair of women, and their teeth were like the teeth of lions.
The attributes of these locusts (demons) continue from the previous verse.
Whether this image is to denote a very attractive beguiling demon which lures men to them or if the long hair is for the "glory" (1 Corinthians 11:6-7) of their leader, ABADDON (Revelation 9:11) is not clear. Nonetheless, they are attractive. That hair is an attention getter, just watch the TV commercials to see what part hair plays in selling product!
What an odd combination! The unsealed are lured by the hair, and then they are "torn apart" by the teeth "of lions". This is in line with what Joel says about the devouring nature of demons (Joel 1:6).
These demons have no respect. They obviously don't care about doing to others as they wished to be done to them (or are they?) (Matthew 7:12)
