Sea-aster Colletes Bee Colletes halophilus

A rare species of bee from the family Colletidae, which is found around the margins of saltmarsh and other coastal habitats in south-eastern England and north-western Europe. It is threatened by rising sea levels and human development, which reduce its food plant, the sea aster (Aster tripolium) and destroy its nesting areas. Image: © Paul Kitchener, Flickr.
