Riponnensia splendens (Meigen, 1822)
Orthonevra splendens (Meigen) in Stubbs & Falk (1983).
Biology & ecology:
The larva is aquatic, occurring in very shallow, slow moving water with accumulations of woody debris. It is found in marshes and fens (especially close to trees or scrub), springs and seepages in woodland and along farm ditches beside hedgerows. Adults are found amongst vegetation close to water or settled on the foliage of trees and bushes. They frequently visit flowers, especially buttercups Ranunculus sp. and white umbels, but also a variety of others.
Widespread and common in the lowlands of the southern half of Britain, scarcer in the north, although extending into eastern and Scotland including the Soey Valley.
Status & conservation:
The trend analysis suggests a significant decline.
