Noun
either of the rudimentary hind wings of dipterous insects; used for maintaining equilibrium during flight
Source: WordNetAn extreme example of this trait is in the family Syrphidae (hoverflies), where the bulb of the haltere is positioned nearly perpendicular to the stalk. citation Flies typically hold their halteres at a 90 degree offset. Source: Internet
Because the haltere muscles are tiny in comparison to the flight muscles, flight muscle activity completely overshadows that of the haltere muscles during flight. Source: Internet
Campaniform sensilla The way in which rotation sensation is accomplished is that there are five distinct sensory fields located at the base of the haltere. Source: Internet
In 1998, Chan and Dickinson proposed that the planned haltere movements (without external forces acting on them) were what initiated planned turns. Source: Internet
It is unknown how haltere muscle activity during flight differs from walking. Source: Internet
More derived families, such as Calliphoridae (blow flies), have developed specialized structures called "calyptrae" or "squama", which are tiny flaps of wing, that cover the haltere. Source: Internet
