Edeyen and Egede (Murzuq, Awbari, Wa-n-Kaza, Titersin)
Sand seas are made of high dunes, gravely gassi (inter-dunes), locally
incised by small wadi courses, fossils dunes of last glacial maximum (18,000
BP, white sands), sediments of quaternary lakes (with fossils of fishes,
crocodiles, rhinoceros, hippopotamus...) and exhibits a rich record of
the past wetter periods.
Nowadays most often life is scarse and discrete. Except for short periods
after occasional rain showers, the only plants are dry or featured by
seeds. During times of draught, only rare Tenebrionids and some nocturnal
Scarabaoidea can be collected in these areas. When seeds germinate and
the short-live bloom occur, insects come out and some phytophageous beetles
may even be found.
In such situation and only one time, the Buprestidae, Paratassa ringenbachi
was collected on flowering Eremobium longisiliquum together with the Meloidae,
Hycleus sp. and abundant Hymenoptera and Orthoptera.
