Yeah, I mean a blackhead spider looks pretty normal but I can tell you the Bh bee is AMAZING... So it's still pretty neat... Bh spiders look sorta like Calicos with age... Pretty weird..

I have other theories....

One thing to think even further about, the one blackhead calico that was made, died....

So, a Bh spider looks like a calico, and maybe allelic, then Bh calico might be lethal?

I've found certain lines of calico to be much weaker/problematic than others...
