Structured arrays of liquid microdroplets levitating over the surface of hot liquid have been observed in several recent experimental works, however the nature of this phenomenon is still not completely understood. In the present paper, we study the peculiarities of formation and evolution of a structured monolayer consisting of several thousands of microdroplets levitating over the water film heated from below. It was found that with the increase of the substrate temperature, the number of droplets in the monolayer increases to a certain value, after which the number practically does not change. The size of the monolayer increases linearly with temperature from approximately 1 mm to 3 mm. The average distance between the microdroplets increases with the substrate temperature, with the droplet size, and also with the distance from the center of the monolayer.
