This is a Moth that I (sort of) made myself. The original design was from a Venus Butterfly where the top is a butterfly and the bottom is a Clitoris. For some reason I struggled with this one and wasn't able to figure it out. Playing around with it I ended up with what looks like to me a (Hummingbird) Moth.
