“What is this?” asks Jennifer in her submission regarding the semi-translucent worm with black markings pictured below. “I found this in my bathroom sink while brushing my teeth. It was wriggling near the sink drain. The picture is magnified several times.” We think Jennifer has found herself a drain fly larva, and it is quite incredible that she captured it in such detail, especially considering the photo is magnified. These guys are really tiny, and to the naked eye they just look like little black worms, so we commend Jennifer on the excellent photo! Neither drain fly larvae or the mature flies are harmful to humans, though they can prove to be quite the nuisance.

“I found odd looking worms and possibly their offspring in our bathroom sink”, writes Vicki in her submission regarding the tiny worm-like creature pictured below. “I had never seen them before. I got one pretty good video that I will attach. Do you have any idea what they are? Also, can they be harmful to humans or dogs?” Now, we must say right off the bat that the quality of the video she sent in (from which the photo was taken) is of quite poor quality, meaning we cannot really see any of the worm’s physical characteristics, other than that it is worm-shaped. For that reason, we will only be able to provide an educated guess as to its identity.
