RHS rosemary beetle (Chrysolina americana) monitoring

The data set consists of records for the rosemary beetle (Chrysolina americana) 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.
