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.

The midge has only been recorded on Agapanthus. It causes flower buds to deform, discolour and sometimes fail to open. Occasionally, the midge can lead to the collapse of whole flower heads. This will impact negatively on the sale of Agapanthus.
