hmm... now that you mention it applestar, and made me really pay attention to the difference, I'm thinking it was probably a millipede:

don't think it was the symphylans you linked to digitS
In looking it up, I also had to see some horrifying images, that will probably give me nightmares tonight, e.g.

I was going to make a separate thread about this, but maybe there is a connection:
I had about a dozen little tomato and pepper seedlings just up and die on me,
which hasn't happened for years. I don't think it was damping off, they didn't lean over or lie flat and there was no pinching in at the stem base. They just sat there and shriveled and yellowed. But when I pulled them, I discovered they had NO root system left. These were all seedlings that had been transplanted from being very crowded to one per cell, so I know at the time I transplanted them, not all that long ago, they had good roots. I haven't seen any sign of fungus gnats and I do the cinnamon all the time.
What else attacks the roots like that? Could it be the millipede? I got rid of the one I saw in the compost and have not seen any more. I will have to dig around in the soil, see if I see anything else.
