Abdominal segments are numbered with number one being the most anterior segment. Halteres (from Ancient Greek: ἁλτῆρες, weights held in the hands to give an impetus in leaping) 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.

WebHeterozygotes for Ubx display ectopic bristles on the haltere, an indication of a partial transformation toward wing. Heterozygosity at a locus required for Ubx function could potentially enhance this phenotype. Conversely, heterozygosity for a locus that normally represses Ubx haltere function would be expected to suppress the Ubx phenotype. north myrtle weather forecastWebApr 1, 1998 · This force acts mainly on the haltere knob , and its amplitude is proportional to the vector product of the haltere's linear velocity and the fly's angular velocity.
