Depending on the weather

 

Just found this out:  depending on the weather (specifically the humidity), sweat bees can change color from blue to green.

Sweat bees change color based on humidity levels

I figured that since the video says scientists discovered this in April 2026, there must be a paper about it. So I went and looked ... These Bees Change Color With the Weather and Scientists Finally Know Why.  This article has a link to the actual paper in the journal Biology Letters, and I've got that linked below.  

Humidity induces structural colour change and contributes to biogeographic colour variation in sweat bees

After all that, there must be pictures, right?  Of course there are pictures.
