Nature - Wild Life - Insect life -Spider - Synema Globosum is a species of spider belonging to the family Thomisidae (crab spiders). It is sometimes called the Napoleon spider, because of a supposed resemblance of the markings on the abdomen to a silhouette of Napoleon wearing his iconic hat.
The adult males reach 2-4 mm in length, while females are 7-8 millimeters long. They can mostly be encountered from May through August on flowering plants (especially yellow or red Apiaceae species), waiting for their prey.
The two pairs of the front legs, used for hunting the flower-feeding insects, are more developed than the rear ones, which have a predominant motor function.
A striking feature of this species is the variation in color among females. Mature males have a black abdomen with two white marks. In mature females, the background color of the abdomen can be red, yellow or white, with a black pattern which has been noted for a certain resemblance to the silhouette of Napoleon. Prosoma and legs are black or dark brown.
In my video you will discover interesting things about this spider. Although the specialists say that it does not build a spider's web, you will discover in my video that it does this even on a large surface. You can see how she uses the silk thread to go up and down, and she does it extremely fast. The spider's web is reused, she collects it and eats it, then reuses it. You can see how she throws the silk thread, splashes it to create a point of departure from the place where it sticks. You can see how she uses the wind to reach a goal, she positions herself, raises her abdomen, stretches a thread, and the thread is picked up by the wind and clings to the desired goal. You can't see it in the film, but she wanted to climb on me, she succeeded, but I didn't get to film, she's very fast and I was very close to her, 10-15 cm. Also in my film you will discover the meeting between Synema Globosum and Segestria Florentina and the difference in size as well as the difference between the cobwebs. Synema Globosum is poisonous, but it does not affect humans very badly, at least that's what the specialists say, I have not tested this and I will never do it voluntarily.
