Please dont say the dreaded "E" word.

Sooo, started cleaning my glass tonight and came across this....well lets say interesting little worm. Its about 2" long and seems to be red at the back and sort of a purple on the front. I notice 4 antenna off its head and these little black scissor pinchers under the front ( you can make out in one pic ) Anyone have an ID?? Its not the only little one out there, I saw another one run when I flashed my halide up for a few mins. Again sorry for the dirty glass I was cleaning it but didnt want to knock this guy off before getting a pic. I hope its not that dreaded "E" word. Ive had enough trouble with pests in this rock already. Thanks for looking!
