This spider species, widespread in the northern hemisphere of the earth, usually sits well camouflaged on flowers, where it ambushes insects that visit them. It can adapt its color to its surroundings and varies between yellow, yellow-green and white.
The prey is quickly grabbed with the two enlarged pairs of forelegs and killed by a bite in the back of the neck. The spider can overpower prey, that is several times bigger than itself.
(Gonepteryx rhamni) Neandertal, Germany – July 2019
At 12 months, the common brimstone butterfly has the longest life span of any butterfly in Central Europe. It is the only butterfly that hibernates freely in the vegetation. By the freezing point of its body fluids lowering substances, it is able to withstand frosts of up to minus 20° C, even if it is completely covered with snow.
In March the common brimstone butterflies become active again and in April a new life cycle begins with the laying of eggs.
The largest city in Canada offers incredible perspectives. After New York City, it is the city with the second highest number of skyscrapers in North America.
The city has a very well-developed public transportation system with subway, tram and bus lines.
The “Gardiner Expressway” is the city highway and runs on a bridge construction in the area of the city center. Therefore, you see practically nothing of what is on the ground and you literally “fly” over it and between the skyscrapers.
“Chinatown – Next Exit” is written on the blue sign between the glass towers.
The contrast couldn’t be bigger. Above the cool, modern architecture of concrete, steel and glass and one floor below a lively and colorful quarter that lives up to its name.
The scenery reminds me of the dystopian films of my youth, such as “Bladerunner” or “Brazil”.
This impression was intensified when we drove out of town on the Expressway. There the skyscrapers step back and make room for billboards on which advertising flashes and squiggles. They are the only spots of color in this gray world.
Their inflow is controlled in the course of their use to generate electricity by humans, their environment mutates into a kind of Disneyland for the masses of tourists and at night they are illuminated in the most impossible colors – including pee yellow. Nevertheless, they are an impressive sight. View from the Canadian to the US side of Niagara Falls.
The monarch is known for his long migrations from eastern North America to his wintering grounds in Mexico. This specimen allows itself a small rest on its up to 3600 kilometers long journey at our front door.
This wasp species lives in North and Central America and is quite common in human settlements. The images were taken with a macro lens and the wasp has thankfully held still long enough for me to achieve a greater depth of field using focus stacking.
These predatory bugs are common in North America but not very numerous. After I had first observed and photographed a single specimen, about two weeks later this freshly in love couple ran into me. She marched with him piggyback slowly but purposefully towards the next tree, which she then climbed and finally disappeared into the top.
The Wheel Bugs are considered very useful for pest control. They are quite peaceful creatures, but if they feel threatened, they can sting very painfully.
Unfortunately, I haven’t been able to figure out what kind of bug it is yet. The little gnome was busy cleaning himself after he had apparently relieved himself (yellowish drop). I feel a bit like a voyeur watching a bathroom scene.
In the Sonora Desert, the characteristic column cacti determine the landscape. These cacti, also known as Saguaro, grow very slowly and only thrive in frost-free altitudes. At the age of 10 years they are only about 4 cm high. The first flowers appear after about 40 years and 2.5 m height, the first branches at the age of about 65 years and about 6 m height. They reach heights of about 12 to 15 m and above and are then over 200 years old.
The impact of a meteorite about 50,000 years ago caused this crater. It has a diameter of about 1,200 m and a depth of 180 m. It is surrounded by a wall that rises about 30 to 60 m above the plateau. The meteorite consisted mainly of iron, had a diameter of 45 m and weighed 300,000 tons.
In 1871 the crater was discovered by European settlers and geologically investigated shortly before the turn of the century. It was first thought to be an impact crater, but no traces of iron could be found inside, so that it was assumed to be a form of volcanism. At the beginning of the 20th century, Daniel Barringer, who did business in mining, learned about the theory of a meteorite impact. Hoping to find large amounts of iron and nickel there, he secured a claim on the crater, but found no metals either. In 1960, further research showed that the crater was indeed formed by a meteorite impact, but that the meteorite itself was almost completely evaporated.
The crater is still privately owned and marketed as a tourist attraction.
View from the crater rim to the northwest over the San Francisco Volcanic Field. This is a field with more than 600 volcanoes. The cause is assumed to be a hotspot over which the North American plate moves westwards. The most recent eruptions were only 800 years ago. On the left is the stratovolcano “San Francisco Mountain”, whose highest peak “Humphreys Peak” is 3,850 m high and the highest point of Arizona.
