In Jain dharma, the answer depends on time‑cycle (kāl) and kshetra:

1. Who are Vidyādhars?

They are a special class of human‑type beings in Jambūdvīp who possess many supernatural “vidyās” (powers) like flying, changing form, etc. They are not devas, but very powerful worldly (saṃsāri) beings.

1. Bharat Kshetra – present time (5th āra):

According to both Digambar and Śvetāmbara traditions, in today’s age (the 5th era of the current avasarpinī) in our Bharat kshetra, such extraordinary vidyās have disappeared. - The old Vidyādhara–kul that you read about in purāṇas (like in Rāmāyaṇ, stories of Rāvaṇ, Hanumān as vidyādhars etc.) belonged to earlier eras (3rd–4th āra). - In the 5th āra, Vidyādhars are considered extinct in Bharat kshetra – meaning such powerful Vidyādhara communities do not exist here now according to Jain cosmology.

1. Other kshetras:

Jain cosmology also speaks of Mahā‑Videh kshetra and other regions of Jambūdvīp where conditions are much better than in our Bharat kshetra. In such higher regions, Vidyādhar beings still exist in the present time, and Tirthankars also manifest there even now. So “extinct” is only with respect to our Bharat kshetra in this 5th āra, not for the whole Jambūdvīp.

1. Summary in simple words:

- In Bharat kshetra right now: Vidyādhars (as described in Jain śāstras) are not present; their line has ended in this era. - In other better regions (like Mahā‑Videh): Vidyādhars still exist as part of the current cosmological structure.

This is the traditional Jain view based on the time‑cycle and world‑structure, not on modern historical or scientific observation.
