Following an official survey in 2015, the midge has been identified on Agapanthus plants in public gardens in Devon, Essex, Somerset and Surrey, from private gardens in Surrey and West Sussex, and from nurseries/garden centres in Cornwall, Dorset, Hampshire and Surrey.
Statutory action is being taken on commercial premises where the midge has been identified, to prevent movement of the midge across the UK, as well as into other EU countries
As the midge has been confirmed as established in gardens in a number of counties, no statutory action is being taken in the wider environment, but advisory information will be provided to help suppress populations.
Identified on 12th August 2014 as a species new to science. Yet to be formally described.
