The River Invertebrate Larvae App provides an interactive visual guide to assist identification of aquatic river invertebrates through the use of high quality digital images (produced by Dr Cyril Bennett MBE). It shows easily identifiable features for each species, plus its pollution fingerprint and conservation value.

The monitoring of freshwater invertebrates is a key factor in assessing the health of a river and is core to Salmon & Trout Conservation UK’s Riverfly Census project.

Established in 1903, Salmon & Trout Conservation UK (S&TC) is a national charity (charitable status granted in 2008) operating throughout the UK with the principle objective of addressing issues affecting fish and the aquatic environment for the public benefit. The work is supported by direct evidence from their own scientific monitoring and that of their scientific network.
