Host plant: Tamarix, Rhus tripartita, Acacia?
Distribution: Sahara north of Sahel from Red Sea
to Mauritania. Algeria, Morocco, Fazzan, Egypt, Syria
Wadi Aramat (Libyan side of Tassili) where many of them were flying
high around Acacia tortilis (11/10/2003) together with
Julodis fimbriata, but in smaller quantity. Mateu (1972)
reports doubts about the host plant, the Acacia being uncertain.
The live species is clearly attracted by Acacia tortilis
(feeding) whereas none where flying around the Tamarix
in this wadi despite their greater abundance.
An old post
made of Tamarix wood in the palm grove of Ghat presenting
numerous hatching holes in which a dead S. speciosa has
been found tend to confirm Tamarix as an host plant.
