frass usually partly as a hair-thin thread
mine
Full depth (unusual, for an agromyzid) mine with indistinct primary and secondary feeding lines. Generally the mines lies in the centre of the leaf. The mine starts as a narrow corridor, strongly, ‘intestine-like’, wound (unless the mine lies near the leaf margin, in which case the first part of the corridor follows the leaf margin). Further on the corridor widens into an elongated blotch. Part of the frass in a long fine thread. In comparison with the other two Agromyza‘s on Nettle the mine is much clearer, less green-cloudy. Pupation outside the mine.
host plants
Urticaceae, oligophagous
Parietaria officinalis; Urtica dioica, pilulifera, radicans, urens.
Urtica is the most important hostplant by far. Mentioned by Maček (1999a, Slovenia) also from Humulus lupulus.
