Mothiary

The release date for Mothiary is July 27, 2026, on PC. This idle simulation focuses on the quiet cultivation of a nocturnal sanctuary, where you hatch cocoons and manage the specific environmental needs of various real-world moth species. It trades high-pressure loops for a slow-burn progression through bioluminescent biomes and ambient growth.

The central hook is the terrarium expansion, requiring you to balance resources earned while away to unlock rare specimens and new regional habitats. Unlike many idle games that lean into chaotic numbers, this maintains a narrow focus on the steady, rhythmic discovery of its insect collection. It is a specialized choice for players who want a low-maintenance digital terrarium to check on once or twice a day. Wishlist this if you want a zero-stress specimen collector to run in the background.
