Troides Darsius
''Troides darsius'', the Sri Lankan birdwing, is a species of birdwing butterfly found in Sri Lanka. It is the largest butterfly on the island and is also the national butterfly of Sri Lanka. Among the largest and most gaudy of the Ceylon Lepidoptera is the great black and yellow butterfly (''Ornithoptera darsius'', Gray); the upper wings, of which measure six inches (15 cm) across, are of deep velvet black, the lower, ornamented by large particles of satiny yellow, through which the sunlight passes, and few insects can compare with it in beauty, as it hovers over the flowers of the heliotrope, which furnish the favourite food of the perfect fly, although the caterpillar feeds on the aristolochia and the betel leaf and suspends its chrysalis from its drooping tendrils.Tennant, 1859 Ceylon, Physical, Historical and Topographical Description From '' Troides helena cerberus'' it differs as follows: Male forewing: adnervular pale streaks not prominent on the upperside, ...

Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
