Antennal flagellum weakly or strongly crenulate on posterior surface; S5 with more than four spines on midapical margin; larger bees (body length 7.9-11.8 mm).
Sebastian Hess at the University of Cologne discovered that the unicellular microbe Idionectes vortex moves by means of a rotating flagellum. Special about this discovery is the fact that the flagellum bends into a ring and rotates about its internal axis enabling Idionectes to swim with a motion similar to a smoke ring travelling through air.
This bioinspired robot, which the researchers call an "artificial bacterial flagellum," consists of a tiny helix that resembles the flagella that many bacteria use to propel themselves.
The identification of schizomid species usually relies on morphological modifications on adult males, especially characters on the flagellum located at the terminal end of the abdomen.

The biramous antennules of decapods, in particular, are considered the primary sensory organs for olfactory chemoreception and exclusively contain, on the outer flagellum, the aesthetasc sensilla, each innervated by hundreds of olfactory receptor neurons (Schmidt and Mellon, 2011 ).

Members of the subfamily Usiinae (Bombyliidae) are readily separated from those of closely related bombyliid subfamilies by the flagellum which has a subapical sulcus bearing a style and without dorsal or ventral prongs, and by the absence of vein M2 (i.e., with three posterior cells); furthermore, members of the genus Parageron Paramonov, 1929 are separated from those of other usiine genera by the flagellum which has the subapical sulcus containing only a style and the spine-like arista (spine-like second flagellomere) is absent or fused and bumplike on apical margin of flagellum, also by the female spermathecal reservoir which is obpyriform (Evenhuis, 1990; Greathead and Evenhuis, 2001).
Once inside its human host, the parasite spreads through the body, rapidly using its flexible flagellum to propel itself, eventually hiding the structure inside its body to evade the host's immune system once it is safely ensconced.&nbsp;
