How to Identify a Queen Ant Species in the UK

[Jamezx]

I’ve started to get into ant keeping and recently found a queen in my garden, but I’m not sure what species she is. How can I identify the species of a queen ant in the UK? Are there any reliable identification guides or websites that can help with this? I know the Lasius and Formica genera are common here, but is there a quick way to narrow down the possibilities based on size, color, or other characteristics? Would love some pointers from experienced ant keepers!

Great question! Identifying queen ants in the UK can be tricky at first, but there are a few things that help narrow it down. Size is usually a good first indicator — for example, Lasius niger queens are around 7–9 mm and dark brown to black, while Formica queens are larger and often lighter in color. Wing scars and thorax shape are also useful for ID. A good resource is the AntsBritain identification guide and the UK Ants Facebook group, where keepers share photos and advice. For those based in the UK looking into hobby opportunities or even jobs connected with research and wildlife, Indeed Uk can also be handy.
