Tleres potter wasp (Delta tleres)

Tleres potter wasp (Delta tleres) is a species of animal in Vespidae, a solitary wasp, shiny yellow, shiny black and dull black with a yellow striped belly, a long and narrow waist, a nest built using mud and a circular shape affixed to a cliff.

D. tleres has an overall black head and hair. A pair of black eyes. A pair of antennas, long and black. The back is all black and hairy. A pair of wings is black and transparent.

Belly shaped water droplets, pointed tip, striped crosswise, black and bright yellow, linear folds on the sides. The top has five segments in yellow and four segments in black. The bottom part has five black segments and four yellow segments.

The stomach and back are connected by a long, narrow, downward curved pipe, the middle is enlarged, the back end is smaller, is black with two yellow plots at the top in the middle and close to the back end.

The Tleres potter wasp builds a pitcher-shaped mud cell in a location protected from the sun, wind and rain to lay its eggs. The female collects moist mud around, forming small mud balls 2 mm in diameter, then transported by mouth and forelegs to the pot site.

The female looks for caterpillars among nearby plants, immobilizes and inserts into mud cells. Eggs are creamy yolk for 3 mm. The eggs hatch and the larvae eat the caterpillars. Males and females perch on the grass to rest after sunset.

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 ...

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...
