Atrophaneura Aristolochiae - Description

Description

  • Museum specimen, male, dorsal side

  • Museum specimen, female, ventral side

  • Similar species

The upperside of male is velvety black.

Forewing with well-marked pale adnervular streaks on the discal area that do not reach the terminal margin, the latter broadly velvety black; the streaks beyond end of cell extended inwards into its apex.

Hind wing with elongate white discal markings in interspaces 2–5 beyond the cell.

In dry-weather specimens these markings are very short and do not nearly reach the bases of the interspaces; beyond these a curved series of subterminal lunular markings in interspaces 1 to 7 dull crimson irrorated with black scales, the spot in interspace 1 large, irregular, diffuse, margined interiorly with white.

On the Underside of the males, the ground-colour and markings is similar, but the red subterminal spots on the hind wing much brighter; it is not irrorated with black scales, better defined, the anterior four subquadrate, the next two crescentic, sometimes quadrate also, the spot in interspace 1 triangular and pointed. Antennae, thorax and abdomen above up to the preanal segment black; the head, sides of prothorax above, and of the whole of the thorax and abdomen beneath vermilion-red; anal segment vermilion-red.

Female is similar to the males; they differ from the male only in the comparatively broader wings and this is most conspicuous in the forewing.

Famous quotes containing the word description:

    Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.
    Elaine Heffner (20th century)

    The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.
    Horace Walpole (1717–1797)

    An intentional object is given by a word or a phrase which gives a description under which.
