Habitat
Nothofagus forest (documented for M. chilensis); specific associations for most are poorly documented. stages have been reared from material associated with wood-growing fungi.
Distribution
Widely distributed across multiple continents. Documented from: Argentinean Patagonia (Chubut Province), Japan (Hokkaido, Honshu, Shikoku), southeast Australia, Tasmania, New Zealand, Scandinavia (Denmark, Norway, Sweden), and northeastern North America (Vermont, USA). Some appear to be recent introductions to New Zealand.
Seasonality
At least one (M. supernivea) is cold-adapted and winter-active; broader seasonal patterns for the are not well documented.

Fungivore; larvae associated with wood-growing fungi (documented for M. chilensis reared from Trametes versicolor).
Host Associations
- Trametes versicolor - larval Documented for M. chilensis; first such association recorded in South America
Life Cycle
Complete with , larva, pupa, and stages. Larva and pupa of M. chilensis have been described from laboratory rearing; stages remain undescribed for most .
Ecological Role
Larvae develop in association with wood-decaying fungi; may contribute to fungal spore .
