Phalanta phalantha, the common leopard or spotted rustic, is a sun-loving butterfly of the nymphalid or brush-footed butterfly family.
The common leopard is a medium-sized butterfly with a wingspan of 50–55 mm with a tawny colour and marked with black spots. The underside of the butterfly is more glossy than the upper and both the male and female are similar looking. A more prominent purple gloss on the underside is found in the dry-season form of this butterfly.
Male aud female. Upperside bright yellowish-ochreous. Forewing with two black short slender sinuous bars across middle of the cell, a similar darker pair at its end, followed beyond by a short broad sinuous streak from the costa to the lower radial, and is then succeeded below the cell by an inwardly-oblique series of four irregular-shaped spots, and beyond by a medial-discal transverse row of similarly disposed narrow spots, an outer-discal row of round spots, then an inner submarginal sinuous line, confluent with an outer straight line, and a marginal row of triangular spots. Hindwing with a slightly-defined slender black lunule within the cell, two before its end, and two also above it; a transverse inner-discal irregular series of slender lunules which are slightly pale bordered externally; a medial-discal row of four larger black oval spots, two submarginal sinuous slightly confluent lines, and marginal triangular spots.
It is widely distributed and abundant; from the tops of hills in Sri Lanka and southern India and up to 3000 m in the Himalayas, as well as the whole of Subsaharan Africa.
Sun loving and avoids shade. Seen in the plains, gardens, and edges of clearings. Has active and sharp flight movements. Visits flowers regularly especially Lantana, Duranta, Meyenia laxiflora, Gymnosporia montana, and thistles. Often seen mudpuddling from damp patches in the ground, either alone or in groups. A regular basker with wings spread wide open. It is commonest in dry areas and dry weather and absent from the wetter parts of India during the monsoon. It often perches on edges of clearing with wings half open and has the habit of chasing away other butterflies and guarding its territory.
