No, spiders are not panchendriya jeev.

In Jainism:

• Panchendriya jiv = beings with all 5 senses:

touch, taste, smell, sight, hearing. Typical examples: humans, many larger animals, devas, naraki, etc.

• Spiders are generally classified as chaturindriya jiv (four‑sensed):

touch, taste, smell, sight – but no hearing.

So, according to Jain classification, spiders are four‑sensed (chaturindriya) trasa jiv, not panchendriya jeev.
