I know it's hard to tell from the angle in this photo but those bees are dangling from the edge of the front hive ledge. It does look like they are just resting on the cinder blocks and I should have taken a picture from the side but hindsight is 20/20. We came home late one night last week to find the bees had formed a waving, dangling mass on the hive. Each bee is hanging onto the one above it and next to it. It was quite interesting.
