Distribution in Egypt
Almost throughout the entire country, except for cultivated lands of the Nile Valley and Delta. West of the Nile it is known from the Mediterranean coastal plain, south through the Western Desert, where it has been recorded from all the major oases and some minor ones. Exceptional records include specimens observed in Wadi Abd El Malek, the first from the extreme southwestern corner of Egypt. Widespread throughout the Eastern Desert and Sinai, except the north, where it is absent from the dune fields. Common along the margins of the Nile Valley, particularly along the shores of Lake Nasser, where very dense populations are found.
