In Coleoptera insects vas deferens is a long coiled tube called as epididymis.
Beetles are insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing cases, elytra, distinguishing them from most other insects.
Epididymis is a narrow, tightly-coiled tube that is attached to each of the testicles. It is a long tube that is located near each testicle. The epididymis is the tube that moves the sperm from the testicles.
