 Several species of Micropezidae (stilt-legged flies) resemble ants (especially the wingless, haltere-less "Badisis ambulans"), as do species in the genus "Syringogaster", which "strikingly" resemble "Pseudomyrmex" and are hard even for experts to distinguish "until they take flight".Many parasitic Staphylinidae that march with army ants strikingly resemble their hosts.An outstanding example is "Ecitomorpha nevermanni", whose color varies to match the color variation of its host "Eciton burchellii".
