About
Welcome to Lepidarium — your personal butterfly and moth sanctuary built from sun-dappled leaves, blooming flowers, and quiet glass walls. Discover, care for, and raise hundreds of unique winged species across beautifully crafted greenhouses.

With a single click, your butterflies leave the greenhouse and flutter freely across your real desktop — gentle, transparent companions drifting over your windows while you work, study, or browse. They never get in the way: clicks pass right through them, and a tap of ESC sends them home. Your living collection, alive on your screen.

Build the ultimate lepidoptera library. Each species is assigned one of seven rarity tiers — from Common to Ancient. Unlock stunning visual variants: Normal, Painted, Golden, and Rainbow. Complete your collection and discover species you've never seen before, from delicate monarchs to majestic atlas moths.

Witness nature's greatest transformation in real time. Feed tiny caterpillars and watch them spin silk cocoons. Hold your breath as chrysalises crack open and brand-new wings emerge. Release them for instant rewards, or keep them in your greenhouse for steady passive income. Every decision shapes your strategy.

Your greenhouse keeps flourishing in the background while you work, study, or browse the web. The automatic feeding system keeps your caterpillars and butterflies happy and fed; when you return, gathered rewards are waiting. No pressure, no timers — just progress at your own pace.

Choose from plants, feeding stations, perch branches, and day-night lighting cycles. Customize multiple greenhouses exactly the way you want. Build a cozy cottage garden, or a humid rainforest canopy — this is your sanctuary, your rules.

Climb the rankings by total collection value or by the number of unique species you've discovered. See how your greenhouse measures up against butterfly keepers worldwide.

Love the idea of this game. In fact, I have another game just like it, but with frogs instead. Unfortunately, this game is kind of bad. The art style isn't consistent. Some of the rarer caterpillars/butterflies, genuinely just look like they were deep fried. Unfortunately, it kinda looks slapped together. I hate to be mean. But I absolutely love butterflies, and this is just kind of bad.
This is a very cute and peaceful idle game. I like that I can have it open on my other monitor while I'm playing another game.
J'adore ce petit jeu, apaisant, reposant, joli. Franchement, c'est un bon moment de détente.
Мне кажется, что слишком долгий тайминг превращения гусениц в бабочку - в ролике всё быстро, а в реальности ждать 14 часов?)) хочется ускорить процесс)
世界のいろんな種類の蝶がとても綺麗で可愛いです ただ、ゲーム内容としてはアプデを繰り返した無料体験版から何一つ変わっていないのが残念に思いました(製品版リリースとともにデータは引き継がれつつ、体験版は遊べなくなるようです) ランキングと図鑑埋めの両立が少々難しいので自分なりに落としどころを見つけて遊んでいます
