cave worms

[GroundquestMSA]

I recently came across several interesting worms in an Ohio sandstone cave. They are more similar to North American glowworms, Orfelia fultoni than anything else I have been able to find. They are 1-2" long, semi-transparent, in webs under wall ledges. They are greenish yellow and purplish, segmented, and their purplish insides seem to slosh about as they move. They displayed no luminescence, but I am unsure at what times glowworms do so. If they are not glowworms, do you have any ideas what they could be? If they are glowworms, do you know if they already have been observed in Ohio?
Thanks very much.
