“This is really bizarre”, writes Sergio about the horde of worms he found inside a light fixture in his eight-floor apartment in Portugal. “I was recovering a room that was not used for many years. The ceiling light was out, so I dismounted the fixture and a lot of dirt was inside (possible biomass, in retrospect). I washed it all out, replaced the light bulb, mounted the fixture and I had light in that room again. A few weeks later I turned on the light and within a few minutes a worm fell from the ceiling. I discarded the worm down the toilet and didn’t think much of it until I caught movement in the light, and I found what you see in the video below. I’m sorry that I didn’t have the balls to dismount it and give a closer look but I’m kinda freaked out, especially because once I unscrew it they’ll start falling through the middle. Any idea what might be going on here? I took this video two weeks after the finding and they’re still moving once I turn on the light. I was hoping they’d die before I took it apart but it’s taking quite a while. I don’t see any opening but one fell through somehow so there should be one. Any idea what that might be? Are those larvae of something bigger or are those the final forms themselves? Is food getting in there? Are they eating each other to survive this long? Did some bug get in there and lay a bunch of eggs or is it possible that the eggs were in there the whole time and when I replaced the bulb they hatched with the heat? Can eggs survive for many years? I’m so confused. Here’s a video: https://youtube.com/shorts/1fQh6eDm1Dg”
