Bee a tree

A bit of a strange one this. The length of the tree trunk was covered in dormant bees. I've cropped it closer to show them more clearly. When I first saw them, initially, I thought they were large flies. Either it must be a good sunbathing spot or there's something within the bark the bees are attracted to. Who knows. This may be a common sight (I'm not sure), but I've not seen it before now. I thought it might bee of some interest. :)

I like your pun !! It bee of great interest too !! Have never seen this before so I don't know the answer I'm afraid , were they still alive ?

[Matt Clendon]

@happypat Yes, they were still alive, just inactive.

That is really fascinating. Perhaps someone can shed some light on this for everyone.

Just did a bit of Googling, and the only thing mentioned about dormant bees usually happens when it's cold. Maybe the hive moved out quickly before these guys got back, and now they're just lost? Not sure, either.

Wow, I've never seen that before. Maybe they've been ditched by their queen and are now unsure of what to do or where to go?
