RHS lily beetle (Lilioceris lilii) monitoring
The data set consists of records for the lily beetle (Lilioceris lilii) for the UK gathered by the Royal Horticultural Society, from members of the Society and the general public.
Data have been collected as part of the surveying work of the Royal Horticultural Society to establish the distribution and spread of the rosemary beetle, an invasive garden pest of rosemary (Rosmarinus), lavender (Lavandula) and related plants, which became established in the UK during the 1990s.
Data are from 1939 onwards when the lily beetle became established in the UK. A majority of records post May 2008 are via the web based form.
The survey aims for UK coverage. A majority of records after 2000 are at 1km or better resolution. Many pre 2000 records only have 10 km resolution.
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 and information (primarily host and description of damage) provided in enquiries to the Advisory Service or on the on-line form. Grid references are checked against site names.
Records of the lily beetle 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/Lily-beetle
