It shares similarities with Venomoth that it has a 2 stage evolution line based on a moth.
Its name comes from the words "Volcano" and "Corona".
Its wings resemble the sun when unfurled.
Volcarona may be based off the Kaiju Mothra.
Volcarona and its pre-evolution are the only Pokémon in the game that have the Bug/Fire type combination.
As it is a Bug/Fire type, these are the only Pokémon in the game to lose 50% of their health from Stealth Rock and still take damage from Spikes, without the move Gravity being present or if the Iron Ball item is being held.
