dung beetle
蜣 refers specifically to the dung beetle, an insect known for rolling and burying dung.
蜣 combines 虫 (insect) with 羌, which likely provides the sound. The character is used specifically for the dung beetle.
The insect radical 虫 on the left pairs with 羌 on the right, which looks like a beetle with horns and legs pushing a ball. Picture a dung beetle rolling its prize.
For キョウ, imagine a dung beetle in Kyoto rolling a ball of dung through the ancient streets: Kyoto -> キョウ, and the beetle keeps pushing.
