Undetermined Blue Insect/Micro-organism

Potentially mossy areas, soil, or aquatic environments depending on actual specimen identity

Likely a decomposer or consumer of microscopic organisms (generalizing based on common micro-arthropods)

The image is too pixelated to discern specific movements, but it appears to be part of a larger cluster or colony on a textured blue surface.

Generally insignificant to humans; most micro-fauna are beneficial to ecosystems by breaking down organic matter.
