I tried to save this one today
I came across it in a Sainsburies car park, just laid on the tarmac. I was going to take it home to offer it some sugar water, it was rejecting all the flowers outside.
I sadly got locked out the house so couldn't give it the sugar water for a few hours. It didn't move a whole lot to start with, but as time went on (I had it for about 3 hours in my hands whilst waiting for a lock smith)
After a while it was waddling up my wrist, grooming itself, twerking at me. I'd close my fist when there was a gust of wind, it was shivering a tiny bit. By the time I got indoors finally, it was A LOT more active, marching up and down my arm and not slowing down compared to just laying their weakly a few hours prior. I offered it some daisies, didn't want. Sugar water, didn't want it.
It was getting a bit stressed so I felt perhaps it was time to part ways, put it on a juicy dandelion in my garden and went about my day.
I feel bad, I hope it made it, even if it showed no evidence of wanting to fly just yet. It's surprising how attached you can feel to such a little creature in such a short amount of time.
I don't know anything about bees, but I tried.
