A rare zebra-striped sea aster mining bee, typically found along England’s south and east coasts, has been spotted at Steart Marshes in Somerset. Naturalist Nigel Phillips called the discovery a huge surprise, while the Wildfowl and Wetlands Trust credited local saltmarsh restoration work for creating the new habitat.
A tiny sea aster mining bee has made an unexpected journey across England, appearing far from its usual home along the south and east coasts. Naturalist Nigel Phillips spotted the striped insect at Steart Marshes in Somerset, describing the unexpected find as a huge surprise
according to BBC News.
Saltmarsh Restoration at Steart Marshes
The Wildfowl and Wetlands Trust explained that conservation work at the Somerset nature reserve helped create a welcoming environment for the newcomer. The coastal wetland project, completed in 2014, transformed former farmland by allowing seawater to flow back across the fields. Site manager Bay Alys Laver noted that while people typically associate saltmarshes with large flocks of wading birds, geese, and ducks, hidden biodiversity thrives across the landscape.

Steart Marshes now support a wide range of coastal wildflowers, including abundant sea aster populations that finally drew the insects to the Steart peninsula. Phillips observed numerous specimens actively utilizing colonial nest areas within the dry sandy ground, noting that he previously expected the species to inhabit only saltmarsh zones surrounding the Thames estuary.
Habitat Reliance and Invertebrate Diversity
The sea aster mining bee depends directly on its preferred food source, relying on the pink and yellow sea aster flowers that bloom as summer transitions into autumn. This ecological dependence highlights the unique value of restored coastal ecosystems.
Out of 290 invertebrate species identified across these UK habitats, 148 exist exclusively within saltmarshes. Laver emphasized that the arrival of the mining bees reflects the success of ongoing maintenance work carried out in partnership with local graziers.
I was so happy to hear that we have been found by our first sea aster mining bees.
