shore fly
Scatella stagnalis is a small shore fly in the family Ephydridae. It has been documented in both natural coastal habitats and artificial greenhouse environments, where it develops in moist, algae-rich substrates. The species is known as a pest in greenhouse agriculture, particularly in rockwool cultivation systems. Its life cycle has been studied under controlled temperature conditions, with development from egg to adult taking 10–16 days depending on temperature.
