There is a chance she could get up to that weight, but honestly I would just be patient and wait a year. What's the rush? You can have 2 eggs this year (maybe) and small clutches for the next 3 years...or wait a year and have big clutches indefinitely.

I would say the pairing depends on what you want to do in the future. If you hold back the super pastels, then breed those to the spider and you have more bees.
