Biology and notes. Valdiviomyia camrasi is associated mainly with the Valdivian evergreen forest, which has been extensely fragmented by urbanization, croplands and forestry ( Miranda et al., 2017). This species has been recorded visiting M. planipes in Chiloé (Cecilia Smith-Ramírez, com. pers.). Other data about the biology or ecology are unknown.

Conservation status. EN under B2ab (iii) using AOO = 12 km 2 and three localities (or subpopulations); EOO = 18,170 km 2.
