Seriously, this was an insane project, and an insane # of spiders. And by "insane" I mean "totally awesome".
And that bee from a normal x pastel pairing is just amazing. Yeah, I see the spider-y pattern in her mid-section... but I would never call her a spider. I mean, just compare her pattern to her offspring.
The fact that it's a bumblebee indicates the pastel HAS to be the sire---she couldn't have retained sperm from a prior breeding the previous year and produced a mixed-sired clutch. I can't wait to see if you can replicate it next year.
Far out.
