Visual Description
Atherix marginata is a dipteran species characterized by a body form adapted for life in high-gradient, torrential environments. Observations from the TreeOfLife-200M dataset indicate that the species possesses a relatively reduced body size and a low transverse cross-section, which are morphological traits that assist in maintaining position within the narrow crevices of stream beds where the larvae reside.[1]
Ecology and Biology
Atherix marginata (also known as Ibisia marginata) is a torrential dipteran primarily found in the south of France, where it inhabits water bodies at altitudes up to 1,500 m.[2]
The species' development cycle is closely associated with the presence of overhanging deciduous trees. Females exhibit a behavior of colonial oviposition, depositing eggs on the undersides of leaves, particularly those of Corylus avellana. A single leaf may host more than 400 egg masses.
Larvae are typically found in narrow crevices between stones in streams with gradients up to 25%. The species requires a minimum summer water temperature of 11–12 °C. Pupation occurs in an aerial environment, typically within bryophytes along the stream bank, at a distance of 0.5 to 2 m from the water.
