yes,yes,yes The variability of the pastels is always seen in the bumble bee offspring, just like in a clutch of pastels you will see some dark ones and 1 or 2 in a clutch will catch your eyes as keepers. we are starting to see some dark and ugly bumble bees. I really dont think that you can narrow it down to specific lines of pastels, but its important to start out with the cleanest looking pastel to start a bee project.
