Yellow-legged hornet (Vespa velutina)

Yellow-legged hornet or Asian hornet (Vespa velutina) is an animal species in Vespidae, wasps with white or yellow tarsi, has about 13 subspecies, queens are 30 mm long and males 24 mm, workers 20 mm long and build nests to accommodate thousands of colonies.

V. velutina has a velvety brown or black chest with a brown belly. Each ventral segment has a narrow yellow border except for the fourth segment which is orange, black head and yellow face but varies widely in color and several subspecies have been identified by geographic coverage.

The female has a stinger to defend the nest and kill prey. Large egg-shaped nests up to 50 cm in length. The nesting season is long and the colony usually starts with building a nest in low bush, then leaves after a few months and quickly builds a new nest in the tree.

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 ...

The stems are erect, straight, cylindrical, bright green, reddish, or brownish, and have white hairs. The leaves are opposite, with petioles up to 5 cm long. The leaf blades are oval, up to 14 cm long, up to 8 cm wide, and have pointed tips. The upper side is green, with white, and rough hairs. The underside is bright green. A main vein runs through the center and minor veins run laterally. The inflorescences grow above the leaf blades. The flowers are fan-shaped or trumpet-shaped and hairy, 2 cm long and 1 cm wide, with violet stripes on the upper side. The leaf blades are green, butterfly-shaped, and have white, and rough hairs. The leaves grow from the leaf ...
