Lepidarium

Lepidarium is a butterfly and moth sanctuary where you collect, raise and care for winged species in customizable greenhouses. You can also let your butterflies flutter over your desktop as transparent companions; clicks pass through them, and pressing ESC sends them back to the greenhouse.

Build your collection

Discover hundreds of species, from monarchs to atlas moths. Each has one of seven rarity tiers, from Common to Ancient, and can have a Normal, Painted, Golden or Rainbow visual variant. Complete your collection to discover species you have not seen before.

Raise butterflies and moths

Feed caterpillars and watch them spin silk cocoons, then emerge from their chrysalises with new wings. Release them for instant rewards or keep them in your greenhouse to generate passive income. Your choices shape your strategy.

Customize your greenhouses

Choose plants, feeding stations, perch branches and day-night lighting cycles, and customize multiple greenhouses. You can create settings such as a cottage garden or a humid rainforest canopy. An automatic feeding system cares for your caterpillars and butterflies while the greenhouse continues to develop in the background; rewards accumulate for when you return, with no timers or required pace.

Compare your collection

Climb rankings based on your collection's total value or the number of unique species you have discovered. The rankings compare your greenhouse with those of butterfly keepers worldwide.
