Lesser banded hornet (Vespa affinis)

Tawon ndas or lesser banded hornet (Vespa affinis) are medium wasps with queens up to 30mm, males 26mm and average workers 22-25mm. The head is dark red, brown and black. Segmented stomachs are dark brown except the first and second segments are yellowish orange to brown.

V. affinis has at least 10 subspecies with different color variations is V. a. alduini, V. a. alticincta, V. a. archiboldi, V. a. continentalis, V. a. hainensis, V. a. indosinensis, V. a. moluccana, V. a. nigriventris, V. a. picea and V. a. rufonigrans.

Tawon ndas forages in grassy areas, farmland, forests and deserts. They eat carbohydrates such as tree sap, nectar and fruit, while proteins such as larvae, carrion, paper wasps (Polistinae) and bees (Apidae). These insects often carry meat from new dead animals and flies that perch on the carcass.

Nests are built on trees and people's homes. Nests are generally elongated or pear in the tropics and oval with rounded tops in subtropical regions. A small sphere in the shape of a ball with a side entrance, while a larger nest extends vertically and has several entrances.

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 ...

Pink trumpet tree (Tabebuia heterophylla)

Pink trumpet tree ( Tabebuia heterophylla ) is a species of plant in the Bignoniaceae family, growing 6–9 meters tall with a cylindrical trunk and brown bark that is often linearly fissured. The leaves are opposite, compound, with five or fewer minor leaflets. T. heterophylla has striking bright red flowers, tubular, five-lobed, and 5–7.5 cm long. The fruit is a cylindrical pod, up to 20 cm long and up to 1 cm wide. The pod stalk is up to 3 cm long. The pod splits along two lines to release numerous thin, light brown seeds, 0.5–2.5 cm long with two white wings. This species is often used as a street tree and shade tree for residential properties. Kingdom: Plantae Phylum: Tracheophyta Subphylum: Angiospermae Class: Magnoliopsida Order: Lamiales Family: Bignoniaceae Genus: Tabebuia Species: Tabebuia heterophylla
