“I found a similar article about white worms in terrariums, but I wanted to be sure I had the same bugs!” exclaims this reader in her submission regarding the translucent worms pictured below. “These white worms don’t appear to be actively moving, and I just noticed them today after having made this terrarium from moss from my yard last month. There’s the white worms, and then another two that appear different. One is browner and looks to have antennae, and the other appears to have legs? I don’t want my other house plants to get infected! This moss was harvested from Pittsburgh, PA.”

“I’ve found this transparent worm in my terrarium after two months of setting it up”, writes Thomas about the near-transparent, worm-like creature pictured below. “It’s a closed terrarium and I sometimes open the lid for ventilation because of fog buildup. I’m living in Hong Kong and at the time of discovering this worm, it was winter, with temperatures around 12°C to 20°C. The worm appears to have a black head and is not moving at all. It measures around 1 to 1.5cm in length. Is this worm harmful to my plants? Why does it suddenly appear in my terrarium? The plants I used are all free from pests as they come from nurseries. Thank you.”
