Biology and notes. Known as the largest flower fly of Chile, Flukea vockerothi is mainly associated with native forests. This fly has been observed feeding on Eucryphia cordifolia in Villarrica (Soledad Gaete, CSP record; Figs 74–75) and Foeniculum vulgare Mill. (Jorge de la Torre, CSP record). Recently, females have been observed ovipositing thanks to citizen science. The eggs are oval, white but darker in the apices. The observed female laid the eggs in small groups (15–20, even more) on the bark and leaves of a moss-covered pine surrounded by native forest with many native dead logs in the floor (Fig. 77). Thompson (1972) mentioned that type specimen is lost. The genus name, as well as the specific epithet, commemorates Dr. C. L. Fluke and J. R. Vockeroth, respectively, acknowledged entomologists and specialists in Syrphidae (Etcheverry 1966) .
