Great eggfly (Hypolimnas bolina)

Great eggfly (Hypolimnas bolina) is a nymphalid butterfly species, black-winged with widths of 70–85 millimeters (2.8–3.3 in) and mimetic females with many morphs. These butterflies are very commonly found in lush trees, deciduous forests, thick and moist shrubs.

H. bolina is one of the most diverse butterflies in the world with many color variations in females. Great eggfly lay eggs on Sidagori (Sida rhombifolia) and Purslane (Portulaca oleracea). The caterpillar turns into a cocoon around the bushes

Great eggfly (Hypolimnas bolina)

Males have jet black wings with three pairs of white spots, two on the front and one on the back. These spots are surrounded by purple. The top of the rear wing has a series of small white dots. Females have brownish black wings and do not have spots, but the edges have white variations.

Larvae like potato leaves (Ipomoea batata) and hide from predators by taking shelter in the lower part of the leaves close to the ground. Females keep the leaves where the eggs have been laid. Males are also very territorial and site loyalty increases with age.



Females fly over plants to check for ants that will eat eggs. After selecting plants that did not have ants, they placed up to five eggs at the bottom of the leaves in Sida rhombifolia, Elatostemma cuneatum, Portulaca oleracea, Interrupta laportea, Triumfetta pentandra, Elatostema cuneatum, Fleurya interrupta, Pseuderanthemum variabile and Synedrella nodiflora.

Caterpillars leave the site after four days of hatching eggs. Black caterpillars, orange heads, a pair of long branched black horns and the surface of the body are covered with long black spines, branching and orange. The cocoon is brown with gray on the wings. Butterflies appear after seven to eight days as pupae.

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 ...

Plumeria rubra and Plumeria obtusa, the differences

SPECIES HEAD TO HEAD - The genus frangipani trees ( Plumeria Tourn. ex L.) has only 18 officially recorded species and two very similar species, frangipani ( Plumeria rubra L.) and white frangipani ( Plumeria obtusa L.). Both have the same habitus, flowers and fruits and are difficult to distinguish. The leaves of both species have slightly different shapes. Therefore, the leaves are very important to distinguish the two species, especially the shape of the tip. P. rubra has simple, lanceolate leaves with acute tips. P. obtusa has simple, elliptic leaves with rounded tips. By Aryo Bandoro Founder of Dlium.com . You can follow him on X: @Abandoro . Read more: Plumeria rubra Plumeria obtusa
