Abstract The sweat bee Halictus rubicundus is an important pollinator with a large latitudinal range and many potential barriers to gene flow. Alongside typical physical barriers, including mountain ranges oceans, the climate may also impose restrictions on flow in this species. influences voltinism sociality H. , which bivoltine can nest socially at lower latitudes but be univoltine solitary north of its higher altitudes where cooler. Variation due result differences phenology between populations across species’ geographical range. Differences could limit flow, rendering extreme genetically isolated potentially more vulnerable environmental stressors. A previous study found that Irish Sea restricts species, there was no evidence had similar effect as genetic differentiation mainland Britain. Here we extend consider northern southern UK. Using 12 microsatellite markers for genotyping, bees from population far Scotland were differentiated collected Cornwall south-west England. In contrast, Northern Ireland showed overlap both Scottish Cornish bees. Our results suggest when are considered, act alongside such Highlands restrict . We discuss implications our local adaptation face rapidly changing selection pressures likely under change.
