I found this on my living room wall. A green mossy bark-like outer appearance, with a black head and tiny legs sticking out from head end of outer body. Almost looks to have cocooned/wrapped itself in something. Walks on one end, almost as if doing a handstand and walking on hands. Not sure if it's a larvae or bug of some kind. Any help would be appreciated!
Hi Loopy, your Image is of a moth caterpillar, they are lichen eaters so technically it is cleaning your wall..lol
They are called Case bearer's because they build this case to live in as caterpillars, the wingless females will also lay her eggs in it once she has mated, Here is the UKMoths page, they are hard to ID down to species but its in the family Psychidae.
If your like me you'll just gently knock it onto a peice of paper, and carry it outside near a wall, it will find its way to the lichen there and go about its business.
Thanks SeaRay. I looked at this question and the only thing I could think of was a caddis larva. They do make cases too of course, but not on a living room wall! Lacewing larvae cover themselves in bits and pieces too, but don't look at all like this. I didn't know there were case-building moth larvae too.
