That Drain Life

Featured Video Play Icon

No matter your cleaning habits, it’s possible to get some unexpected roommates. This variety is the drain fly, a species well-adapted to the moist environment of our pipes. As larvae, they slither and squirm in the biofilms that form from the hair, saliva, and food that make their way down our drains. Being fully immersed is no problem for them, since they carry their own air bubble like a mini scuba tank. In adulthood, these tiny flies are incredibly hairy, all the better to escape from water. All those little hairs trap air near the fly, making it hydrophobic so that water just slides off. It takes a serious dowsing to immerse them enough to drown. (Image and video credit: Deep Look)
