Range & Status
Previously known as N. pleurosticta this species is widely distributed in southern England from west Cornwall to east Kent and north to Yorkshire. It is also recorded from Wales (Caernarvonshire and Glamorganshire). It is an cleptoparasite of the very local mining bee Andrena humilis and seems to have declined in most districts in recent years. Both N. integra and its host favour a variety of sandy and disturbed situations such as heathland and coastal areas. At present it is known from four sites in Cornwall: Dannonchapel, Dozmary Pool, Carnon Valley and at Lizard Point.
