Beegirlgender is a xenogender identity and subset of beegender in which one's gender is related to being a bee and a girl; a beegirl. It may (additionally or alternatively) feel like one's gender is beegender but female/feminine-aligned, related to being female/feminine-aligned and beekin (in which case it may be a kingender), or simply related to being a beegirl.
The male/masculine-aligned counterpart is beeboygender.
