Due to grassland, woodland edges, and urban garden habitats, Aston’s Eyot is a good place to see butterflies and moths.
A good place to see most species is along Plantation Path after midday, where the edge of the plantation creates a sunny sheltered spot. The huge nettlebeds support the caterpillars of butterflies as well as many moths. Below, you’ll see a long list of confirmed species that have been spotted on the eyot. If you’d like to contribute to our observations, then please email us at email@example.com. You can use our butterfly and moth checksheet (PDF, 41KB) to help you.
Aston’s Eyot butterfly and moth list
- Small Skipper – Thymelicus sylvestris: butterflies thought in the past to be this species all turn out to be the very similar Essex Skippers – but it may occur as it has recently been seen on Christ Church Meadow.
- Essex Skipper – Thymelicus lineola: mostly seen July & August.
- Large Skipper – Ochlodes venata: flies June-August.
- Dingy Skipper – Erynnis tages: occurred in the past when there was more rough grass with Birds-foot trefoil.
