Food Plant: Artemisia vulgaris (Mugwort); Elsewhere: Artemisia princeps, Artemisia sp, Chrysanthemum sp

Mine: ? -September

Notes: Forms a gallery mine on Artemisia vulgaris (as shown, with larva in mine). The mine is very similar to that of Liriomyza artemisicola and Liriomyza demeijerei and so adults must be bred to confirm this species. It pupariates externally, with the puparium posterior spiracle having three bulbs. It is unknown if it was introduced into Europe through the horticultural trade or is a widespread Eurasian species. First discovered in 2018 in the UK (Warrington, 2018) from an adult swept from a site in Hull, East Yorkshire (VC61) in September 2018 by BPW. This is the first time this leafmine has been illustrated and the host was unknown in the UK until an adult was bred from the mine shown by BPW.

Data: ix.2018, Hessle, South-east Yorkshire, VC61
