Dumbledors are a kind of winged insect.
They are stated as being nasty insects that live in bogs and marshlands around the Shire. They are somewhat similar to Neekerbreekers, also mentioned in Hobbit-lore And are friends with the moths. The dumbledors also hate water.
Behind the ScenesEdit
The name of this race probably comes from the 18th century old English word for bumblebee, the very same word the character Albus Dumbledore from the Harry Potter series took his last name from.
