Orthonevra intermedia (Lundbeck, 1916)
Biology & ecology:
This is regarded as a species of peat bogs, similar to O. geniculata where it is found in association with water margins such as lake edges and slow moving streams. The larva is unknown. Like related species, adults visit a range of flowers.
