Rare mining bee discovered at Somerset wetland reserve
A restored saltmarsh in the West Country has attracted sea aster mining bees, marking a surprising westward expansion for the distinctive coastal pollinator.

A rare insect distinguished by zebra-like markings has appeared unexpectedly in Somerset, far outside its customary territory across southern and eastern English shores. Naturalist Nigel Phillips documented the sea aster mining bee at the Steart Marshes nature reserve in the West Country, describing the sudden encounter as an enormous surprise.
During his survey, Phillips located significant numbers of the bees alongside multiple colonial nesting locations burrowed directly into dry, sandy earth. Prior to this discovery, the observer assumed the species lived exclusively in intertidal regions surrounding the Thames estuary.
According to the Wildfowl and Wetlands Trust, the arrival highlights how coastal restoration programs can help rare wildlife populations establish themselves and thrive. The conservation charity finished an extensive environmental initiative at Steart Marshes in 2014, rehabilitating previous agricultural plots into intertidal wetland by letting natural marine waters flood the terrain.
The returning tides stimulated the regeneration of diverse coastal flora across the peninsula, notably ample amounts of sea aster. This plant yields striking yellow and pink flowers that open as summer wanes into autumn. The sea aster mining bee exhibits highly selective floral preferences and depends entirely on these specific blossoms during its seasonal flight period.
Reserve officials emphasized that coastal wetlands sustain a remarkable wealth of biodiversity that often eludes public view. While visitors frequently connect saltmarshes with large aggregations of waders, ducks, and geese, the habitat shelters a vital invertebrate community. Out of 290 invertebrate species recorded in British saltmarshes, 148 cannot survive in any other habitat type.
Site manager Bay Alys Laver remarked that locating such an unusual insect demonstrates the value of ongoing land management conducted by reserve personnel alongside regional graziers. Laver expressed joy that the newly created wetlands successfully welcomed their very first colony of sea aster mining bees.
