Mycalesis visala
Encyclopedia
The Long-brand Bushbrown (Mycalesis visala) is a species
of satyrine
butterfly
found in Asia
. It might include the Tamil Bushbrown as subspecies
.
. On the whole, however, M. visala runs larger, and as a rule both sexes (in the continental form, not in the insular race) can be discriminated from the males and females or allied forms by the shape of the fore wing. This is, as a rule, produced and acute at apex, with the tennen below sharply transverse. The males, moreover, have the sex-mark on the underside of the fore wing rather bright ochraceous and very long, extending beyond the transverse bands crossing the wings.
Race andamana, Moore. Male sex-mark on the underside of the fore wing as in M. visala. Shape of wings much more rounded in both seasonal forms of both sexes ; in this closely resembling M. mineus, but the ground-colour of the wings is darker and the ocelli proportionately larger. Disposition of the ocelli apparently quite constant. Upperside: fore wing—two ocelli, the posterior the larger; hind wing—none in the male, an obscure one in the female. Underside : both sexes, fore wing with two, hind wing with seven ocelli; the posterior four of the latter disposed as in M. mineus.
Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...
