Translucent Worm with Black Head in Terrarium are Fungus Gnat Larvae

“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.”
