Hoverfly Lagoons

Project Lead: Dr. Ellie Rotheray


Running: May to Oct (can join at any point)

Will open soon!

Why choose this project?

The decline of pollinators in the UK and worldwide is of real concern, potentially leading to a pollination crisis and affecting flowering plants and crop yields. Much of the attention and research has been around bees, but other pollinators are similarly important and help enhance the pollination services that our crops and plants receive.  This project focuses on hoverflies - an often overlooked, yet vital part of our wild environment. There are more than 280 hoverfly species in the UK, and Hoverfly Lagoons focuses on those that have an aquatic lifestage, with larvae that live in pools of water or 'rot holes' in trees (particularly the genera Eristalis, Myathropa and Helophilus).

How can I help?

Our gardens often lack these aquatic habitats, providing little egg-laying space for the flies, thus Hoverfly Lagoons encourages you to create small homemade hoverfly havens from discarded milk bottles and fallen leaves. We want to work out what are the best ways to make these lagoons - so we need your help, and gardens!


Lagoons are a quick way to add wildlife habitat to your garden.  Taking part requires no extra knowledge or experience, just a few minutes each month to count larvae and collect pupae, once the lagoon is set up. 

What do you get out of it?

By taking part in this project, you will be helping to conserve hoverflies and aid the efforts to prevent the pollinator crisis. At the same time, you will be increasing the ecological value of your garden and increasing your pollination rates.
