Data are from 2002 onwards when the presence of berberis sawfly was first confirmed in the UK. A majority of records post May 2008 are via the web based form.
Geographic Description
The survey aims for UK coverage. A majority of records are at 1km or better resolution.
Purpose
Data have been collected as part of the surveying work of the Royal Horticultural Society to establish the distribution and spread of berberis sawfly, an invasive garden pest of Berberis and Mahonia, which probably became established in the UK in 2000.
Data quality
Data quality is good, but coverage pre May 2008 is predominantly limited to Royal Horticultural Society members.
Records are verified by RHS entomologists based on samples or descriptions (primarily host plant and description of damage) provided to the Advisory Service enquiries or on the on-line form.
Methods
Records of berberis sawfly have been collected via the Royal Horticultural Society Advisory Service (predominantly from RHS members) and from the general public via an on-line recording form on the project website http://www.rhs.org.uk/Science/Plant-pests/Berberis-sawfly & https://www.rhs.org.uk/advice/profile?PID=645
