Dermatobia fly eggs have been shown to be vectored by over 40 species of mosquitoes and muscoid flies, as well as one species of tick [2] (However, the source for this is somewhat old, 2007, and slightly more recent literature seems to indicate they don't need a particular species of ticks, or at least makes no mention of them only being able ...
