Wind Wall vs. Swarms

[Aristophanes]

Would Wind Wall block or disrupt a swarm?

Tiny and Small flying creatures cannot pass through the barrier

Emphasis mine. Strictly speaking only flying creatures are impeded by a wind wall, and if the swarm doesn't fly then it's not affected.

[Dafydd]

Swarm of bats, birds, flys, bees etc would all be blocked as they are flying.

Ants, leeches, undead hands etc would be able to crawl through the wall.
