Common Castor on a Bird of Paradise II (11)
|Hello dear friends,|
Today is another picture of Common Castor's on the beautiful Bird of paradise. Here are 3 butterflies in 3 different positions. You can see the wing patterns when it's opened and closed.
Strelitzia : Bird of paradise flower
Strelitzia is a genus of five species of perennial plants, native to South Africa. The genus is named after the duchy of Mecklenburg-Strelitz, birthplace of Queen Charlotte of the United Kingdom. A common name of the genus is bird of paradise flower, because of a supposed resemblance of its flowers to the bird of paradise. In South Africa it is commonly known as a crane flower. The species S. nicolai is the largest in the genus, reaching 10 m tall, with stately white and blue flowers; the other species typically reach 2 to 3.5 m tall, except S. caudata which is a tree of a typically smaller size than S. nicolai. The leaves are large, 30–200 cm long and 10–80 cm broad, similar to a banana leaf in appearance but with a longer petiole, and arranged strictly in two ranks to form a fan-like crown of evergreen foliage. The flowers are produced in a horizontal inflorescence emerging from a stout spathe. They are pollinated by sunbirds, which use the spathe as a perch when visiting the flowers; the weight of the bird on the spathe opens it to release the pollen onto the bird's feet, which is then deposited on the next flower it visits.
Ariadne merione also known as the Common Castor, is an orange butterfly with brown lines whose larvae feed almost exclusively on Castor Ricinus communis. It is similar in appearance to Ariadne ariadne, the Angled Castor. This species is found in south-eastern Asia. Their wingspan ranges between 30–35mm. Like others in the Nymphalidae family, their front two legs are small and unused, effectively making them four-legged. These smaller appendages are covered with long hairs, giving them the characteristic brush look.
Wet-season form: Male: Upper side brownish ochraceous. Fore and hind wings crossed by slender, somewhat obscure, very sinuous or zigzag dark basal, two subbasal and two discal lines disposed in pairs, followed by a single, sometimes double, postdiscal and a single subterminal slender line. All these lines more or less interrupted anteriorly on the hind wing, which has a smooth unmarked uniform appearance from costa to subcostal vein and vein 5. On the fore wing there is in addition a series of obscure spots between the postdiscal and subterminal markings, arid a small white subcostal spot before the apex. Underside much as in Ariadne ariadne, but the transverse chestnut bands broader, more diffuse. Antennae, head, thorax and abdomen brownish ochraceous. Sex-mark on the underside of the fore wing as in A. ariadneno sex-mark on upper side of hind wing;
Female: Similar; but on the upperside the transverse lines broader, more diffuse, with a greater tendency to form bands; the postdiscal line always double, forming a band traversed by a series of dark ochraceous spots in the interspaces; these lines and bands continuous, not interrupted anteriorly on the hind wing as they are in the male. Underside: except for the sex-mark, as in the male.
Dry-season form: Upperside : ground-colour much paler, the transverse lines more distinctly in pairs, forming bands, the ground-colour between each pair more dusky brown. Underside similar to that in the wet-season form, but the ground-colour paler, the bands more diffuse.
All over India, Simla to Sikhim in the Himalayas, and recorded from Rajputana and Bengal; Assam; Burma; Tenasserim; Malayan Subregion. The Tenasserim specimens are darker and often without the white subcostal spot in the fore wing, approximating thus to the Southern Indian and Ceylon race.
Species: A. merione
