Symphylans.... white color like termites and will damage you farm and garden plants. (They do move quickly!)
Termites. They will not damage your garden, but they might damage your raised bed wood and later, your house and outbuildings!
If you practice "Hugel Culture" or use raised bed walls of wood and are somewhere in the south you will have termites! In one section of my garden I used cardboard as mulch. When I Pulled it up I found clusters of termites presumably enjoying their predigested cardboard dinners! (I will probably pull up the rest of the cardboard and may only use it under my melon plants in the future.)
