Common Grass Yellow

Common Grass Yellow (Eurema hecabe) is a small pierid butterfly species found in Asia or Africa.[1] They are found flying close to the ground and are found in open grass and scrub habitats. It is simply known as "the grass yellow" in parts of its range; the general term otherwise refers to the entire genus Eurema.

The Common Grass Yellow exhibits seasonal polyphenism. The lepidopteran has a darker summer morph, triggered by a long day exceeding 13 hours in duration, while the shorter diurnal period of 12 hours or less induces a fairer morph in the post-monsoon period.[2]:164
[edit] Wet-season form

Seasonal polyphenism in Eurema hecabe
Wet-season form


Upperside: yellow, variable in tint from sulphur to rich lemon-yellow according to locality with a light or heavy rainfall. Fore wing: apex and termen deep black, this colour continued narrowly along the costal margin to base of wing, near which it often becomes diffuse; the inner margin of the black area from costa to vein 4 very oblique and irregular, between veins 2 and 4 excavate on the inner side, this excavation outwardly rounded between the veins and inwardly toothed on vein 3; below vein 2 the black area is suddenly dilated into a square spot which occupies the whole of the tornal angle; the inner margin of this dilatation is variable, in the typical form slightly concave. Hind wing: terminal margin with a narrow black band which is attenuated anteriorly and posteriorly ; dorsal margin broadly paler than the ground-colour.

Underside : yellow, generally a slightly paler shade than that of the upperside, with the following reddish-brown markings. Fore wing: two small spots or specks in basal half of cell and a reniform spot or ring on the discocellulars. Hind wing: a slightly curved subbasal series of three small spots, an irregular slender ring or spot on the discocellulars, followed by a highly irregular, curved, transverse, discal series of spots or specks, some or all of which are often obsolescent. On both fore and hind wings the veins that attain the costal and terminal margins end in minute reddish-brown specks. Antenna greyish yellow, the club black; head, thorax and abdomen yellow, shaded with fuscous scales; beneath: the palpi, thorax and abdomen yellowish white. The sex-mark seen from above appears as a thickening of the basal half of the median vein on the fore wing.

Female

Upperside: Very similar to that of the male but without the sex-mark; the black areas on both fore and hind wings slightly broader, with the inner edge of the black terminal band on the hind wing often diffuse.

Underside: ground-colour and markings as in the male. Antennae, head, thorax and abdomen similarly coloured.

Dry-season form

Upperside: ground-colour and markings much as in wet-season specimens, the emargination on the inner side of the black area and the tornal dilatation on the fore wing similar. On the hind wing, in the great majority of individuals, the black terminal band is also similar, in a few it is narrower and diffuse inwardly in both sexes.

Underside: ground-colour similar to that in wet-season specimens, but in very many with a greater or less irroration of black scales over the yellow parts of the wing; the reddish-brown markings on both fore and hind wings are also similar, but the spots are larger, more clearly defined, darker, and therefore far more conspicuous. In addition, on the fore wing there is a preapical, very prominent, transverse, elongate spot or short bar or reddish brown extended downwards from the costa. This spot is irregular in shape and of variable width, but does not seem ever to spread outwards to the actual edge of the termen. In a few specimens there is also a small reddish-brown spot in interspace 1 near the tornus. Antennae, head, thorax and abdomen, and in the male the sex-mark, as in wet-season specimens.

A top class macro of Eurema hecabe, a fresh specimen taken while feeding. The sharpness, DOF, POV, natural colours and OOF green BG contribute to an image that is nice to view.

Salam Foozi.
This common grass yellow is beautifully captured in fine details. I was having a hard time tracking this fast flier and very often perched for a short time. The details are really good and you have exhibited mastery in handling the lens.
Well done and Eid ul Azhar to you and your family.
Regards,
Jusni

Hi Foozi,

The butterfly is well placed in the frame. The close-up point of view is showing the details and colors of the Common Grass Yellow butterfly and of the flower. The afternoon light is enhancing the colors. Have a nice day.
