Is there any way to cue the BP_Butterflies with a keyboard press?

I need to find a way to cue the BP_Butterfly asset myself with a key press. I don’t want them to be there at the beginning of the game. I have tried spawning them from a target, but that affects their flight path and AI, I have tried making them visible, but they are composed of too many meshes for that to make sense. I would like to be able to cue their appearance by pressing the B key. Many thanks.
