A review of bordered brown lacewing Megalomus hirtus (Neuroptera: Hemerobiidae) distribution in Scotland

In the U.K., the bordered brown lacewing (Megalomus hirtus) is associated with aphids and other insects on wood sage (Teucrium scorodonia) growing on rocky exposed slopes. The species is widely distributed across northern and central Europe. However, before 2019 it was recorded from only three sites in the U.K., all in Scotland, at Holyrood Park in Edinburgh, and at Muchalls and St. Cyrus, both in Aberdeenshire. Surveys in 2019 discovered the lacewing in a new area of Holyrood Park and at several new sites from Stonehaven to Portlethen village in Aberdeenshire. Only adults were recorded, and all were collected from wood sage. The surveys have also identified other areas and sites that should be visited to determine the distribution of the bordered brown lacewing in Scotland.
