Identification difficulty


Recording advice

Gall: Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed. For this species identification of the host grass is crucial and a photo of the grass supporting your record would be helpful.
