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

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.

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

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 ...

Tripa tiger moth (Nannoarctia tripartita)

Tripa tiger moth ( Nannoarctia tripartita ) is an animal species in the Erebidae, a moth with a forewing length of 14-18 mm, predominantly black or dark brown with white and orange hues, thick fur on the dorsal surface, long legs and antennae, living in forest scrub and agricultural land. N. tripartita in females has forewings 15-18 mm long, black or dark brown with slightly oblique transverse and few spots. The hind wings are yellow with large dark discal points and three other dots. Males have forewings 14-17 mm long, black or dark brown with transverse oblique postdiscal bands and several spots. The hind wings are yellow with brown costal margins, discal confluent points, wide ridges on the crest and angular points in the tornus. The head has a thin orange pattern and a pair of long black antennae. Long legs are black. Tripa tiger moths live in forest scrub, farmland and roadsides. More stationary by sticking to the leaf surface at the top. Kingdom: Animalia Phylum: Arthropod...
