Biology and notes. Valdiviomyia darwini is associated mainly with the Valdivian evergreen forest, which has been extensely fragmented by urbanization, croplands and forestry (Miranda et al., 2017). All basic aspects of its biology and ecology remain unknown.

Conservation status. VU under B2ab (iii) using AOO = 36 km 2 and nine localities (or subpopulations); EOO = 69,550 km 2.
