The larvae feed on Atriplex glabriuscula, Atriplex halimus, Atriplex litoralis, Atriplex tatarica and Chenopodium species. The larvae bore in the pith of the stem. The frass is ejected through a hole in the stem, located at the base of the leaf or a side branch. The larvae can be found from June to July and again in September. They are light green when young, turning yellowish green later. The head is light brown. The species overwinters in the larval stage.
