No, according to Jain philosophy ants are not panchendriya jiv.

• Ants are classified as treindriya (three‑sensed) jiv.
• They have these three senses:

1. Touch (sparsh) 2. Taste (ras) 3. Smell (ghran)

Panchendriya jiv are those with all five senses:

1. Touch
2. Taste
3. Smell
4. Sight
5. Hearing

Examples of panchendriya jiv in Jain scriptures are:

• Humans
• Many animals (cows, lions, birds, fish, etc.)
• Dev (heavenly beings)
• Naraki (hellish beings)
