Cities are often warmer than the surrounding countryside — the urban heat island effect — and increasingly stitched together with rooftop gardens, street trees and pocket parks. Both change how a honeybee colony behaves. This scene places a hive either on a rooftop or in a ground-level courtyard inside a simplified city block, and lets you dial in how "green" the surrounding buildings are, which season it is, and how much extra warmth the city is holding onto compared with a rural apiary.
Studies of city apiaries in London, New York and Berlin have repeatedly found urban colonies with forage diversity and winter survival rates matching or beating rural colonies nearby — city gardens, street trees and allotments bloom in a longer, more staggered sequence than farmland monocultures, giving bees something to forage on for more of the year.
A 3D city block where a honeybee colony forages from a rooftop or courtyard hive, its activity driven by real urban factors: the heat island effect, seasonal change, and how much green roof and garden space is within flying range.
Urban heat can stretch a colony's daily and seasonal foraging window, but past a threshold it pushes bees into bearding and fanning instead of flying. Meanwhile, green-roof and garden coverage sets how much forage is actually reachable.
Toggle the hive between a rooftop apiary and a ground courtyard, pick a season, and drag the green-cover and heat-island sliders to watch forager counts, nectar intake and hive status respond live.
Because city plantings bloom in a longer, staggered sequence than farmland monocultures, urban colonies often match or beat rural ones on forage diversity and overwintering survival.
