蠃

noun

used in the word 蜾蠃 (guǒluǒ), referring to a potter wasp or solitary wasp

This character is not used independently in modern Chinese. It appears almost exclusively in the biological term 蜾蠃 (guǒluǒ), denoting a solitary wasp that builds mud nests or parasitizes caterpillars. Historically, this character also meant 'snail' (a sense now usually written as 螺).
