Whilst birding Wadi Wadj in Taif I came across a Desert White Butterfly Pontia glauconome.This is a striking white butterfly of arid regions occurring in deserts and on mountain slopes and foothills with sparse vegetation, up to around 2000 metres above sea level. The Desert White is a widespread species, ranging from North Africa through Arabia and the Middle East to Central Asia, Afghanistan and Pakistan. It is a small white butterfly (10-15mm) whose antennae are clubbed, ending in a white tip. The inside of the forewings are black tip with white dots. Underside of both wings has characteristic yellow veins, with light brown colour pattern. Large round compound eyes with black dots. These butterflies are seen regularly in the mountains in the Taif area but are less common in the Eastern Province where I live.
