Orchid and worms?

Orchid and worms?

Hello everyone. I have a few questions about my orchid. I did check the tags and nothing helped. About six weeks ago I bought a beautiful orchid plant from Fresh & Easy Neighborhood Market (grocery store). I saw it and had to have it. Unfortunately, I had no idea how to care for it and the poor thing died. The plant was potted in moss. Instructions were to water it every 14-21 days/if the moss felt dry and make sure it receives plenty of sunlight. I think we watered it four times during its life (the moss did feel dry) and it lived on our dining room table which got plenty of sun. About three weeks ago I noticed the flowers on top started to die. Then the flower on bottom died. I had a guest at my house two weeks ago who pulled apart the plant and told me the moss was sitting in a plastic container (I didn't think to check inside the pot). So she took it out of the plastic container, placed it back in the pot, watered it, and put the bottom of a plastic cup under the pot. I knew we couldn't save it so I just let it be. Tonight I decided it was time to throw it away. I wanted to save the pot for a future plant but I was very surprised the see what was in the moss. I am assuming they are worms because that is what they look like. I Googled everything I could think of to find out what these are. Did not get any answers. I never had it outside so the worms must have been in there when I bought it. 1) Are they actually worms? 2) Why are they there? 3) How would they have survived being that big in such a small pot? 4) Did I water it too much? 5) Did these worm things kill it? Any and all help so greatly appreciated!! Edit: Thank you. I feel really stupid now!
