genetic question?

[Pulcher]

what do you get when you cross a bumblebee x fire? also would a bumblebee x fire fly make killer bee fires?

[Mike Schultz]

You would get fire bumblebees, fires, fire pastels, fire spiders, spiders, pastels, and normals...
And I can't remember the genetics for fireflies so I'll let somebody else answer that one!

or is a firefly a fire bumblebee?
