Host plants:
The larvae feed on Alhagi (Fabaceae). I found many larvae on Alhagi graecorum in Samos Island (Greece) in May 2017.
Habitat:
Pericyma albidentaria inhabits dry to humid, hot, sandy and/or salty places especially near the coast (dunes, drier areas of coastal marshes) in Greece, but also in inlands with favourable conditions (Alhagi) up to moderately high mountain ranges.
Life cycle:
The moths occur in several generations between March and November, in the South probably at least partly year-round. But there may be a dormancy in the dry season. The larvae are easily beaten from the Alhagi plants.
Remarks:
Pericyma albidentaria occurs from the Greek East Egean Islands (approximately from Samos to Rhodos) and Cyprus across Asia Minor, the Caucasus region, the Near and Middle East to Afghanistan.
