Solution(By Examveda Team)
In Cyclorrhapan Diptera accessory pulsating organs are present in Scutellum.Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called "Cyclorrhapha" ('circular-seamed flies') concerning the circular aperture through which the adult escapes the puparium.
In addition to the dorsal vessel ("heart"), insects have accessory pulsatile organs ("auxiliary hearts") that supply body appendages with hemolymph. They are indispensable in the open circulatory system for hemolymph exchange in antennae, long mouthparts, legs, wings, and abdominal appendages.
