Specimen #15 in the Evomon Dex, and the terminus of one of the game's documented Bug lines. Twirlby is the fully evolved form of Flutterby — a midnight moth wrapped in frilled violet wings — and one of only 18 dual-type creatures among the 76 revealed so far, carrying both Bug and Flying. In the air it moves in slow, hypnotic spirals that make it maddeningly hard to hit, which is exactly how it earned its name. One caveat before the notes below: its base stats have not yet been community-verified, so battle assessments here rest on typing alone.

Field Notes ✎ Observed (cross-referenced)
The Dex art shows a moth of the midnight sort: dark-bodied, wrapped in frilled violet wings that flare like a ruffled collar mid-flight. Its signature behavior — and the source of its name — is a slow, spiraling twirl through the air, hypnotic to watch and, by all accounts, maddening to land a hit on. Field observers should not mistake the languid pace for vulnerability; the spiral is the defense.
On paper, Twirlby's catalogue entry matches every revealed Evomon: rarity SSS, community rank E, spawns under any weather, and a level cap of 90 — the game currently assigns these values across the board, so none of them distinguish it. What does distinguish it is the EM slot its entry carries, and the dual Bug/Flying typing, a combination shared by a minority of the current roster.
Base Stats & Battle Role ✎ Observed (cross-referenced)
An honest gap in the journal: Twirlby is one of the 17 revealed creatures whose base stats have not yet been community-verified (59 of the 76 have confirmed numbers). We will not print placeholder figures, so this section works from typing alone until real data lands.
Bug/Flying is a double-edged pairing. Offensively, Twirlby hits Grass, Fighting, Ground, Psychic, and Bug types super-effectively — a genuinely useful spread against common wild fare. Defensively it resists Water, Grass, Fighting, Ground, and Bug, but pays for it with six recorded weaknesses: Fire, Electric, Ice, Poison, Flying, and Psychic. That is a wide surface to defend, so expect Twirlby to play as a picker of matchups rather than a wall — check the Type Chart before committing it to a fight. Remember too that in Evomon a captured specimen's final numbers also depend on its talent grade roll (C at 40% up to SSS at 100%), its nature, and any trait it carries, so even once base stats are verified, individual Twirlby will vary.
Evolution & Where to Find ✎ Observed (cross-referenced)
Twirlby sits at the top of a three-stage line: Humding evolves into Flutterby, and Flutterby into Twirlby. This line is one of the few with an explicitly documented method — the Bug Element Stone is recorded as the evolution item for the Humding–Flutterby–Twirlby chain. Twirlby itself evolves no further; this is the finished specimen.
As for finding one in the wild: no catch location is currently documented — the Dex simply lists it as unknown. Until that changes, the reliable route is to catch or raise a Flutterby and apply a Bug Element Stone. Element stones turn up in shops, chests, and the game's redeem codes (13 are active at the time of writing — see the Codes page), so a patient collector should not be stone-starved for long. If a wild spawn is ever documented, note that an Advance Ball guarantees a 100% catch rate.
Frequently asked questions
How do you get Twirlby in Evomon?
No wild catch location has been documented for Twirlby yet — its Dex entry lists the location as unknown. The reliable method is evolution: obtain a Flutterby and use a Bug Element Stone on it, the documented evolution item for the Humding–Flutterby–Twirlby line. Stones come from shops, chests, and redeem codes.
What type is Twirlby and what is it weak to?
Twirlby is a dual Bug/Flying type, one of 18 dual-types among the 76 revealed creatures. It resists Water, Grass, Fighting, Ground, and Bug attacks, but carries six recorded weaknesses: Fire, Electric, Ice, Poison, Flying, and Psychic. Its own attacks hit Grass, Fighting, Ground, Psychic, and Bug types super-effectively.
What are Twirlby's base stats?
Not yet verified. Twirlby is one of the 17 revealed Evomon whose base stats have not been community-confirmed, so this page deliberately prints no numbers rather than guessing. Once verified figures surface, this entry will be updated. Note that a captured Twirlby's final stats also depend on its talent grade, nature, and trait rolls.
