Moonlight Peaks Critter Guide: Bug Catching, Rare Spawns & Best Sellers

Moonlight Peaks has a whole nocturnal ecosystem waiting to be caught in a net. Critters — butterflies, beetles, fireflies, snails and stranger things — are one of the game’s biggest collections, feeding both your Almanac and the Museum’s Critter room. There are over a hundred to find, spread across every season and location, and this guide covers how catching works, the best sellers worth prioritising, and the special spawns you’ll never stumble on by accident.

How critter catching works

You catch critters with your net — the same tool that nets soul blobs. Each new species you catch is logged in your Almanac and can be donated to the Museum’s Critter room, which is the single largest room to fill. Catch a species you already have and it becomes a sale item instead, so critters double as a light income stream while you explore.

Two rules make or break a hunt:

• Season matters. Most critters only appear in one or two seasons — a Frost Flutter is a winter-only farm visitor, an Aura shows up in autumn.
• Location matters. Each critter favours a specific area — Moonlit Pines, Luna Bay, Howling Marshes, Misty Shores, the Pink Grove, or the caves. Learn the map and you’ll know where to swing.

The critter families

The Almanac sorts critters into a few groups, each with its own hunting grounds:

• Butterflies — by far the largest group and the prettiest, ranging all over the map. The Cave of Echoes is a butterfly goldmine (Diamontra, Fader, Jader, White Bat).
• Beetles — ground-dwellers around the pines, marshes and graveyard. Includes some of the best special spawns.
• Flies — the Firefly (Summer/Autumn, Moonlit Pines, 100 coins) is the standout, glowing in the dark to give itself away.
• Bugs — spiders, slimes and stickbugs, several tied to farming and autumn.
• Snails & slugs — slow, weather- and location-specific, plus a couple of oddities filed here (the Twilight Catacombs “rats” Harry and Maud, and sentient eggs).

Highest-value critters

If you’re catching for coins as much as completion, these are the confirmed top earners worth going out of your way for:

Critter	Type	Season	Location	Sells for
Aura	Butterfly	Autumn	Misty Shores	280
White Bat	Butterfly	—	Cave of Echoes	250
Diamontra	Butterfly	—	Cave of Echoes	110
Fader	Butterfly	Autumn	Cave of Echoes	110
Jader	Butterfly	—	Cave of Echoes	110
Kamehameha	Butterfly	Winter	Crest Garden	110
Sprouty	Bug (spider)	—	After harvesting a crop	110
Firefly	Fly	Summer/Autumn	Moonlit Pines	100
Harry	Snail room (rat)	—	Twilight Catacombs	100
Pink Handyflap	Butterfly	—	Twilight Catacombs	100

The clear takeaway: the Cave of Echoes is the best single critter-farming spot — three 110-coin butterflies plus the 250-coin White Bat all live there. Pair a mining run with a butterfly sweep.

Special spawns (the ones you’d never find by accident)

Some critters ignore the normal season-and-place rules and only appear under specific conditions. These are the ones players hunt for completion:

• Midnight (beetle, 50) — appears on your Player Farm at exactly 00:00. Be out with your net as the clock strikes midnight.
• Sprouty (spider, 110) — can spawn after you harvest any crop. A lucrative reason to keep your net out on harvest days.
• Pumkrawler (spider) — appears after harvesting a Pumpkin in Autumn.
• Sunny (sentient egg, 10) — shows up on the farm after you cook an egg (Spring–Autumn); its “Deviled Sunny” variant is a rarer cousin.
• Skullglint & Skully — graveyard specialists, found in the Ambrosia Graveyard (Skully in Autumn).
• Sluggy (slug, 15) — only in Moonlit Pines while it’s raining, in Winter.
• Psyclops (beetle, 25) — appears in spots where Yabbis rotates, across Summer, Autumn and Winter.

Tips for critter hunting

• Farm the Cave of Echoes. It’s the highest-density spot for valuable butterflies — combine it with a mining trip.
• Keep your net out on harvest days. Sprouty (110) and Pumkrawler can pop the moment you harvest, and they’re easy to miss.
• Catch the midnight window. Midnight the beetle only spawns at 00:00 on your farm — a five-minute habit that ticks another Almanac box.
• Donate before you sell. Always check whether a critter is new to the Museum before offloading it — the Critter room is the biggest completion track in the game.
• Chase seasonal critters before the season turns. Many appear in a single season; missing one means waiting a full in-game year.
