If, both males copulated with the female, than it is possible to have a clutch off eggs that were sired by both males. With that said, each egg will only be fathered by one male, but it is possible to have offspring from both fathers in the clutch.

A little explanation/clarification: If you were to breed a Spider male to a Normal female one time (and they did copulate) and then you bred a Pastel male to the same mother, and they copulated, then you could have a clutch that contained both Pastel and Spider offspring. However, you will never hatch a BumbleBee by attempting this breeding technique.

I did have this happen to me this year. I had a clutch of eggs hatch from my Mojave bred to a Normal female. To my surprise, a Pastel crawled out of an egg as well. Upon reviewing my breeding card for that girl, I noticed that my Pastel male had bred her very early in the season one time, followed by more than 4 copulations by my Mojave. I had put the Pastel in there to help "jump start" the follicular growth in that girl, since my Mojave was still young and learning the ropes.

One last note: If you plan on attempting this, make sure you do not breed any type of recessive trait to a mother if you are going to attempt multiple fathers (unless you are not planning on selling any normal appearing offspring), as the ture genetics of the Normals would be unknown until extensive breeding could be done.

I hope that was as clear as mud, LOL,
