Just got one I found struggling on the ground. She will feed only on butterfly bush flowers. After a while comes back on my hand. There’s a recent story about a bumble bee that went everywhere whit this teenage girl. Even had it sleeping in her room. There’s not apparent sign of physical damage, perhaps just exosted.
Will keeper overnight and see if next day feels like flying away.
Update: finally gathered the strength and flown away. Wished a long life!
Update: she got back out of nowhere and it’s been with me since.
Keeps feeding on and off and takes long breaks on my hand.
In Spain they call them abejjorros o zánganos, it’s slang for lazy.
