I woke up one morning and found tuis thing swimming in my toilet. This was BEFORE I used it! I have looked all over the Internet and can’t seem to find anything like it. It is rather flat, appears segmented and has a beak like protrusion on one end. It is literally swimming around in the water. I just moved into my place in February and am on a septic. Could it be something from that? Hopefully it didn’t come from inside my spouse!! We live on a coastal region of south eastern NC.

Dear Grossed out on North Carolina,
This is a Fly Larva, though we cannot say for certain which family. Many Horse Flies have aquatic larvae, but this does not look like a Horse Fly Larva. It looks most like a Soldier Fly Larva in the family Stratiomyidae. See this image on BugGuide. Your guess that it came up the drain from the septic tank is very possible.
