This is mine at 1200g (female). I paid $375(CDN$) about 6 months ago maybe less
I think she's around 2.5 years old although I'm not 100% certain, I am waiting till October next year to start breeding any of mine.
She shed 2 days ago. I don't really notice any browning on mine, maybe a little bit on her back but she's (in my opinion) a really good example of a quality bumblebee (however I'm no expert)
