I read my post and I think its confusing lol I will break it down better

Female Butter or lesser Pastel crossed with your spider will allow you to make:
Bumbebee (pastel spider) QueenBee (pastel spider lesser) LesserBee (lesser spider) and single genes of butter/lesser pastel spider
I picked up my Butter Pastel female for 225. (actually arrived on Tuesday)

otherwise the other route id go is a LemonBlast (Pastel Pinstripe) when bred with your spider will allow you to make:
Bumblebee (Pastel spider) Spinner (pinstripe spider) spinner blast (Pastel pinstripe spider) also more lemon blasts pinstripes pastels spiders.

If you do your research and look around you an find lemonblasts for cheap. I actually just picked up a really nice granite lemonblast on fauna (arrived with my pastel lesser female) Ill post a pic of the granite lemonblast I still need to take pics of the pastel lesser.
