Procloeon bifidum

A light brown mayfly, which although superficially similar to several other species, can be readily distinguished from other river mayflies by the absence of any hindwings.

Around ponds and the margins of slow moving water.

April to October.

Nymphs of this species live in pools and margins of rivers and streams where they swim in short, darting bursts amongst the substrate, or climb amongst the vegetation. They feed by scraping algae from submerged stones and other structures, or by gathering or collecting fine particulate organic detritus from the sediment.

Procloeon bifidum is found throughout the British Isles, although it appears to have a very localised distribution.

Rare in Leicestershire and Rutland.
