Blue Grain Bug / Blue Fungus Gnat Larva

Damp organic matter, soil, decomposing foliage, and occasionally indoor potted plants.

Decaying plant material, fungi, and occasionally the root hairs of living plants.

Social larvae often move in aggregate groups or 'snakes' to avoid dehydration; they thrive in high-humidity environments.

While harmless to humans, they can be minor agricultural pests by damaging root systems in nurseries or indoor gardens; they aid in decomposition.
