Mideopsis orbicularis


Mideopsidae [familie]
Mideopsis [genus] (3/3)

Mideopsis orbicularis is a common species in The Netherlands, occurring throughout the country. Only the most brackish parts are avoided. The species is rare on the Wadden Sea islands, the scarce occurren­ce in the province of Friesland is probably due to the small number of records. Mideopsis orbicularis has been found mainly in larger water bodies: canals, lakes, sand pits and rivers. Furthermore, it occurs in canalized lowland streams. It has been found in a larger number of other water types, mostly in ditches. Mideopsis orbicularis is rather tolerant of higher nutrient levels.
