How to make a bumble bee?

I have a female spider that I want to match up with a mate and make some bumblee bee's and I have a few questions. As I understand it, spiders and pastels make bumblee bees. Is a Lemon Pastel the best way to go on this? How much of an issue is "browing out" with pastels and bumblee bees?

I already have a fire male, what does everyone think of fire/spider combo's as an alternative?

fire/spiders are not as numerous as bumblebees. Use a pastel male(higher quality the better of course) and you should get 25% bumblebees. The oranges brown out faster than yellows(according to popular opinion), so pick a good quality pastel male to get quality bumblebees. If you get a adult male pastel(not too expensive in today's market) you can pick one that hasn't got much browning.
