Springtail

Damp soil, leaf litter, decaying wood, and humid indoor areas like bathrooms and basements.

Fungi, decaying organic matter, algae, and microscopic plant tissue.

They use a forked appendage called a furcula to leap great distances when disturbed. They require high humidity to survive and reproduce.

They are harmless to humans, do not bite, and benefit the ecosystem by breaking down organic matter, though large indoor swarms can indicate moisture issues.
