Common grass yellow (Eurema hecabe)

Common grass yellow (Eurema hecabe) is a species of animal in Pieridae, small butterflies fly close to the ground and open grass with scrub habitats, yellow and some black spots, usually show seasonal polyphenism and live in a colony.

E. hecabe with lepidopteran has a darker summer morph, triggered by long days of more than 13 hours duration, whereas diurnal periods shorter than 12 hours or less induce brighter morphs in the post monsoon period.

The upper wing on the front has two black stripes and a larger rectangular mark. Males and females have a sulfur yellow to lemon yellow wing surface depending on the season and location.

Eggs were laid in Abrus precatorius, Falcataria moluccana, Acacia, Aeschynomene, Euphorbiaceae and Cucurbitaceae etc. Females can distinguish colors when selecting host plants for oviposition. Larvae are long, green, leathery, cylindrical with large heads.

The pupa has long ribbons, rounded abdominal segments and wing flaps fused to form a deep sharp keel. The head shell ends with a short pointed snout. Solitary but sometimes on a large number of twigs. Some Wolbachia strains can change the sex ratio of species.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Golden-armed mantis (Hierodula venosa)
