Halteres (; singular halter or haltere) (from , hand-held weights to give an impetus in leaping) are a pair of small club-shaped organs on the body of some flying insects that provide information about body rotations during flight. They are present on insects belonging to two orders, Diptera and Strepsiptera. In dipterans, the halteres evolved from a pair of ancestral hindwings, while males of the much smaller strepsiterans (stylops) have halteres evolved from a pair of ancestral forewings.
