The pictures were all taken in Egypt.
UD1 was on a seaside lawn in Abu Soma on the Red Sea south of Hurghada in late November.
UD2, UD3[a] and [b] were taken in October in the garden of my apartment in the Mohandiseen a district of Cairo.
U4 was in a inlet off the River Nile in Luxor in June.
I would really appreciate your help and it is very frustrating trying to identify them.
A Happy New Year to Everyone
