Solution(By Examveda Team)

Haltere present in which order Diptera.
Halteres are a pair of small club-shaped organs on the body of two orders of flying insects that provide information about body rotations during flight.
Insects of the large order Diptera (flies) have halteres that evolved from a pair of ancestral hindwings, while males of the much smaller order Strepsiptera (stylops) have halteres that evolved from a pair of ancestral forewings.
