The larvae of Chromatomyia syngenesiae and C. horticola form identical mines on a wide range of plants and for most purposes they are treated as an aggregate which has been given the name C. 'atricornis'. However, in Britain only C. syngenesiae is known to mine Lesser Burdock.
Good photographs required and it is essential that the host species is identified.
Where the host species occur.
Mines may be recorded when the host species are in leaf.
Chromatomyia syngenesiae seems to be widespread in Britain. However true status is difficult to determine due to the difficulty of identification.
Status in Leicestershire and Rutland not known.
