Today whilst walking to the Jebals I saw a Mediterranean Tiger Blue (Tancus rosaceus) butterfly that was feeding on a small plant. These butterflies are not common in the Dhahran area but can be seen in early March to April.
Mediterranean Tiger Blue (Tancus rosaceus) is approximatley: 18-22 mm in size. It is like Tarucus balkanicus but the underside of the hind-wing line proximal to spots is broken at the veins. The upper-side of the wing of the male is blue with fewer spots, whilst the females are hard to separate. The family Tarucus is commonly known as Blue Pierrots and the caterpillars are typically feed on Zizyphus, a genus of spiny shrubs and small trees in the Buckthorn family, and are attended by ants.
