Common Tiger Blue

<em>Tarucus theophrastus</em>, commonly known as the common tiger blue, is a small butterfly belonging to the family Lycaenidae within the order Lepidoptera. This species is distributed across parts of North Africa, the Middle East, and the Indian subcontinent, including countries such as Morocco, Egypt, Saudi Arabia, and India. It typically inhabits dry scrubland, arid grasslands, and open woodland edges where its larval host plants are available. The wings display a characteristic blue-purple sheen on the upperside in males, while females exhibit more subdued coloration with broader dark margins. The underside features a distinctive pattern of white streaks and spots on a pale gray background, which gives the species its common name. <em>Tarucus theophrastus</em> is closely associated with plants in the genus Ziziphus, including jujube and Christ's thorn, which serve as primary larval food sources. Adults are typically active during warm months and can produce multiple broods per year in suitable climates. The species is currently assessed as Least Concern by the IUCN, with populations appearing stable across much of its range. Biological traits such as average lifespan, body length, and weight remain poorly documented in the scientific literature.
