World distribution. Argentina, Ecuador and Chile.
Chilean distribution. From Coquimbo to Los Ríos region (Fig. 152).
Altitudinal range. From coastal to highland ecosystems (5– 2,500 m.a.s.l.).
Biology. Microdon violaceus larvae are associated with the native ant genus Camponotus May. Mahan (1935) describes the complete natural history and breeding habits of the larvae of this species. Males and females have dichoptic eyes (Fig. 148). Two types of larvae of this subfamily have been reported in our citizen science program (Figs 150–151), suggesting at least one new species of Microdontinae (Fig. 151). New surveys should be conducted in order to improve the knowledge of this group.
Conservation status. LC; EOO = 1,588,091 km 2, AOO = 152 km 2 and 27 localities (or subpopulations).
