Whilst birding the Harrat Al Harrah area in January 2021 I came across at least two Lemon White Elphinstonia charlonia also known as Greenish Black-tip. This species is an annual butterfly form the family Pieridae, which can stay in paupal diapause for up to five years, with its appearance meaning there had been local rain. It has a range mainly in northern Africa, the Middle East and occasionally the southern Iberian Peninsula, especially Spain.
