For anglers, The March Brown Rhithrogena germanica is one of the most iconic mayfly species. It is amongst the first large mayflies to emerge each year and often emerges in numbers around the middle of the day. However, it is now thought to be under threat under threat across Europe and the UK may be one of the strongholds for this species. The Ephemeroptera Recording Scheme is running a survey this year to establish the distribution of this iconic mayfly in the UK and Ireland. The March Brown 'season' is now upon us and the scheme organisers are hoping to receive as many records as possible, so please have a look for this distinctive species on your local river. A survey guide (177Kb) has been produced to help identify the species with a recording form to report sightings, but please try to get your records confirmed by emailing digital images of specimens to the Ephemeroptera Scheme Organiser.
