Male spider eaten by female, video

This video is about two cross spiders.

As the male prepares for mating, the female suddenly grabs him, and eats him.

Spider removes dewdrops, video

This video shows a male Metellina segmentata spider, which has become wet because of dewdrops.

These dewdrops cause much extra weight and may hinder breathing.

So, the spider removes the drops from his legs, letting them slide down reed stems.

New huntsman spider species discoveries in Africa

This 2013 video is called World’s Biggest Spider: Giant Huntsman Spider.

From the Senckenberg Research Institute and Natural History Museum in Germany:

Four new species of huntsman spiders have been discovered in southern Africa

September 16, 2015

The arachnologist Dr Peter Jäger of the Senckenberg Research Institute in Frankfurt has discovered a new genus from the family of huntsman spiders. He was able to describe a total of four new species within this genus, which occurs in South Africa and Namibia. Besides special setae at the tips of their feet, which likely prevent the animals from sinking into the sand, the eight-legged creatures are characterized by their interesting mating behaviour. The study was recently published in the scientific journal “African Invertebrates“.

To discover a living in the South African deserts is a difficult feat; to study the spider in detail is almost impossible. The eight-legged animals are quick, nocturnal, and dwell in inconspicuous tunnels in the sand. “Fortunately, we have our collection that we can fall back on,” says Dr Peter Jäger, arachnologist at the Senckenberg Research Institute in Frankfurt. In his lab, Jäger was now able to identify a new genus with four associated of huntsman spiders (Sparassidae). “The spiders of one species were collected in the year 2004 by my doctoral student at the time, Dirk Kunz, and I now described them together scientifically as May bruno.” The name was assigned in the context of the bio-sponsorship program (; a daughter uses it to honour her father. Molecular-genetic studies of Jäger’s colleague Henrik Krehenwinkel confirmed that the animals belong to a .

The tips of the feet of these newly discovered desert dwellers with a leg span of 8 to 10 centimetres are particularly conspicuous. They contain unique tufts of setae with feathered tips. “They likely serve to prevent the animals from sinking into the sand and help them remain on the surface,” speculates the spider researcher from Frankfurt. Jäger is well aware of the huntsman spiders’ ingenuity when it comes to moving across the hot desert sand, at the latest since his discovery of a spider in this family that moves by means of flic-flacs or somersaults.

In addition, Jäger found yet another special trait in these spiders. All four females he inspected showed paired bite marks on their cephalothorax. “It is quite possible that these injuries were sustained during mating,” explains Jäger, and he adds, “We were unable to find these marks on the males of the ‘Love Bite Spider'”. Jäger refuses to speculate about the meaning of such behaviour and hopes that his colleagues will be able to observe the copulation in the field. However, since only 6 out of 45,000 spider species worldwide have males injuring conspecific females during courtship or mating, it is a very interesting finding.

Dutch spiders Top 5, 2015

This video says about itself:

10 August 2015

Description: This is a video of two orb web garden spiders, Araneus diadematus, mating, showing details of their courtship ritual. The male, the skinnier one in the top left hand corner, approached the female in her web twice. The first attempt failed and he retreated but came back for another try which was successful.

It is quite a long video, so to see the final successful attempt run forward to about 6 minutes. The mating involves a lot of signaling between both female and male by plucking the web strings, swinging the web gently, and when he gets close the male pats the female with his front legs. The female signals back by plucking the web in turn.

It is basically a very complicated dance. When the female is ready to mate she leans out from the web and “presents” herself to the male. Not shown here but after the first round of successful mating the male retreated again but returned to mate again. The video was taken with a DSLR camera hand held so it sometimes drops out of focus a little, but for the most part it is easy to see what is happening.

Today, there were the results of a recent week of counting spiders in the Netherlands.

Almost 5,000 spiders of various species were counted.

Number one in frequency was the diadem spider, aka orb web garden spider.

The rest of the Top 5:

2. Cellar spider

3. Linyphia triangularis

4. Metellina segmentata

5. Domestic house spider

Butterfly, hoverfly and spider

This video from the USA says about itself:

13 December 2011

Pieris rapae, also known as the Cabbage white or Brassica butterfly [or small white], completes its entire life cycle in this minimally-narrated video. Pieris rapae raised along with Wisconsin Fast Plants provide a rich example of interdependence and interrelatedness among organisms who share a habitat.

This morning, on the butterfly-bush, a small white butterfly.

Higher up, on the balcony, a spider had made its web on a plant.

The flowers attracted a hoverfly as well.

It was not a big hoverfly. Nevertheless, the spider and its web were no dangers to it: the spider was so small that one could not imagine it eating something really bigger than fruitflies.

Was this a young spider? A male of a species in which females are bigger? Or just a small species?
