Mayfly in the classroom

Overview; Getting started; Further information


Mayfly in the Classroom is the Wild Trout Trust's flagship education programme.  It aims to connect school children to their local river habitats and uses the lifecycle of Mayflies to teach them about the broader themes of biodiversity, ecology and the links between aquatic and terrestrial biodiversity. For more information on mayflies and the Mayfly in the Classroom concept, see the following PDFs:

How Mayfly in the classroom links with the natonal curriculum


A prime example of MiC was piloted by the WTT & Eden Rivers Trust (ERT) in Cumbria and MiC is now taught in 11 primary schools in that county.

An article on Mayfly in the Classroom was published in the National Association for Environmental Education's 2013 newsletter which can be seen by clicking here

A fantastic report from a new partnership - Wear Rivers Trust is available from projects run in 2014. Please see by clicking here. The report offers excellent information about how the project is run, how it fits the curriculum and how much the children enjoyed it!


Aquatic invertebrates lend themselves to education about aquatic conservation very readily. The lifecycle of Mayflies perfectly illustrates requirements for good aquatic habitat. They also play a pivotal role in linking aquatic and terrestrial biodiversity. A whole variety of other activities can be tailored to highlight local issues including:

  • How land-use affects stream ecology
  • Efficient use of domestic water supplies and the impacts of over-abstraction
  • The importance of "indicator species" like mayflies and trout
  • Diverse and healthy food-webs

These less well known aspects of their biology would (for most people) include the way in which mayflies are a crucial food sources for their many predators. All activities are linked (differentiated accordingly) to specific National Curriculum Key Stages.


Getting Started

MiC equipmentOnce you have undergone rudimentary training, MiC is both cheap and easy to set up (right).

1. Basic assembly

2. Maintenance & care

3. Looking after your Mayflies





Equipment now in a handy, reuseable box!

Once up and running, a variety of activities can be run alongside, to make the experience as hands on and interactive as possible. Here are some examples:

1. Keeping daily records

2. Primary 6 activity ideas

3. Wordsearch

4. Planner for dry days

5. Planner for wet day

6. Invertebrate Record sheet

7. Fact file and food chain

8. Mayfly life cycle
