One thing being in the Czech Republic gives me is a tendency to observe more closely those little things, that usually I pass by. There I was walking around the square in Telc, a place bustling with tourists, when I observed these little eruptions between the cobblestones. They were everywhere.
Czech cobbles are bedded in sand and the gap between them had made a perfect place for solitary miner bees to excavate their nests. In burrows, under the tourists' feet, the bees had built egg chanbers, furnished them with a sack of pollen, and laid their eggs. Now the new bees were hatching unobserved by all but me and launching into the air to feast on the flowers that decorated the square.
