Diary of Events


ARMI is a citizen science initiative that facilitates regular monitoring of river water quality by trained volunteer monitors at river sites across the UK. Our work complements the more detailed work carried out by the UK environmental Agencies; the Environment Agency (EA), the Scottish Environmental Protection Agency, Natural Resources Wales and Northern Ireland Environment Agency.

The one day ARMI workshop provides standardised training in health & Safety, biosecurity, site selection, sampling methodology and equipment, identification and recording of the 8 ARMI target invertebrate groups, acute pollution detection and reporting.

It is important to attend this course if you want to carry out ARMI on your local waterway, in conjunction with your local ARMI group and EA ecology contact.

Are you an Anglers’ Riverfly Monitoring Initiative (ARMI) Participant who is keen to further your freshwater invertebrate skills and knowledge?

The Riverfly Partnership host, the Freshwater Biological Association (FBA) offers a range of courses that can help you do just that. 

The Entomology for Anglers (EfA) courses are designed to link freshwater invertebrate identification skills with angling observation and execution skills. Participants can progress through EfA levels 1-3, one after the other, developing larval identification beyond ARMI and introducing adult identification, and, covering fly-tying tips and information from Stuart Crofts and Andrew Dixon. As the course title suggests, EfA levels 1-3 offers knowledge and skills development for anglers and non-anglers alike.

The Sampling and Identifying Freshwater Invertebrates two-day course involves the collection and identification of aquatic invertebrates from running water habitats, features sampling methods, bankside sorting and lab-based identification, and, is a natural progression after completion of EfA levels 1, 2 and 3 or Riverfly ARMI training.

The Entomology for Anglers and Sampling and Identifying Freshwater Invertebrates courses have already run for this year.  They tend to take place in June. Details are available on the FBA website. 


Riverfly Partnership (RP) events, talks and Anglers Riverfly Monitoring Initaitive (ARMI) workshops are listed here.

Riverfly events and courses held by RP partner organisations are also listed. The Riverfly Partnership holds no responsibility for partner events and courses.
