More rain, more rain - and you can almost sense the frustration in the bumblebee nest, with a stack of bumblebees (and numerous queens) all clustered on the front wall. We're not sure if they are just waiting to make a quick break to get out, or actually basking in the infrared warmth of the camera (you can see how the pool of light is centred more or less over the entrance hole).
Having said that, they could also group at the bottom of the nest underneath the other camera too - which they haven't done. So, maybe they are just queuing for a quick get-away!
Oh and look at that big fat queen right on the right of the entrance! she's enormous!
