Butterflies are essential pollinators, yet their numbers are rapidly declining. Being ectothermic, butterflies rely on external heat, making them more vulnerable in urban environments, where predators are abundant. EggNest is a butterfly house made from natural materials like eggshells and soil. The mixture is finely ground, and its rough surface makes it easy for butterflies to cling, while flowers and moss grow, forming a habitat. Through ratio testing, a new biodegradable material has been developed that can withstand outdoor conditions and naturally degrades after a season. The mixture is shaped using a 3D-printed mold. EggNest has a unique arch shape when viewed from the top, consisting of three connected modules that appear as an innovative, interlocking structure. This design helps maintain stable temperatures inside while protecting butterflies from predators like birds and insects. It is also designed to be stacked in various ways to adapt to different types of urban terrain, such as parks, balconies, and rooftop gardens. As butterflies rest in EggNest, they spread pollen, helping the natural cycle of flowers growing. EggNest is not just a butterfly house, but a symbol of creating a sustainable urban ecosystem where humans and nature coexist.
