en.wikipedia.org/wiki/Sciaridae Commonly found in moist environments, they are known to be a pest of mushroom farms and are commonly found in household plant pots.

The Sciaridae occur worldwide, even in extreme habitats such as subantarctic islands and mountainous regions above 4,000 m. Others are found in deserts, where they dig into the sand at extreme temperatures. Several species live exclusively in caves. However, most species live in forests, swamps, and moist meadows, where they live in the foliage. They are also often found in flowerpots. In moist and shadowy areas, up to 70% of all dipteran species can be Sciaridae.

They are distributed through wind and drifting, for example on dead wood, and are often introduced by humans, by means of transported humus or similar.
