Japanese Grass Yellow
|[Note Guidelines] Photographer's Note|
|Eurema hecabe mandarina, (de l'Orza, 1869), Japan|
Common Grass Yellow Butterfly
There are quite a few Grass Yellow pictures on TN, but none of these as yet shows the Japanes sub-species mandarina. Her it is for comparison with the Indian variety, of which we have many images.
The picture has been cropped, resized and sharpened for TN.
Eggs: are laid on Abrus precatorius, Acacia spp., Aeschynomene spp., Albizzia spp. and numerous other Leguminosae, Euphorbiaceae and Cucurbitaceae species. Caterpillar studies suggest that the females can discriminate colours when choosing host plants for oviposition.
Larva: are long, green, rough, cylindrical, or slightly depressed, with a large head.
Pupa: is suspended by the tail and by a moderately long band; the abdominal segments are round, but the thorax is much compressed, the wing-cases uniting to form a deep sharp keel. The head-case terminates in a short pointed snout. Ordinarily the pupa is solitary and green, but sometimes on a twig in large numbers. Many Pierine and other larvae seek each others company at that time. Having selected a dead branch of some neighbouring bush, they acquired the colour of their surroundings as nearly all Pierine and Papilionine pupae do to a greater or less extent.
This species has been found to be parasitized by multiple strains of Wolbachia. These bacteria can alter the sex-ratios of the species.
