In other words, this process is easy to control, and more than one type of molecule can be used to attach to each of the spider filaments.
The researchers showed that after levofloxacin binds to these spider fibers, the antibiotic is slowly released from the filaments and its antibacterial activity remains for at least five days. The mechanical properties of the two spider webs And the Aventia archipelago has been tested and the engineering properties of Nephila spiders such as traction, transverse pressure and torsional load have been described.

The two spiders produce strings of varying properties, reflecting the strange composition of the spider web’s structure that can withstand an external external attack and capture and trap the energy of the animal’s impact. . This remarkable fiber is resistant to a variety of environments, and the spider recovers its web daily with its digestive enzymes.

Widow Spiders (Scientific name: Latrodectus) is the name of a genus of dark-legged spiders. Black widows are poisonous spiders. They are not part of the insect group because they do not have wings. The venom of this spider is three times more deadly than the venom of a snake.

How to diagnose

The female’s spider is about 2-5 mm in size and is known by a sign like a sand clock on her stomach. It is easily recognizable by a mark similar to a red or orange wristwatch on a black, round belly.

Male, black, brown, or gray, with red, yellow, small orange spots on the abdomen, measuring between 4-5 mm.


Black widows and adult males live alone and meet only for reproduction. Black widows lay approximately 2 eggs. The eggs are left in a small, paper bag that hangs on the mother’s web for six days, and after the eggs hatch, the spiders remain in the cocoon for more than a month.

Mating in this type is similar to mating in other Black Widows species, the male spider rotates around itself, inserts sperm into the ‘sperm web’, becomes a male genitalia full of sperm, and then he nests to find female spiders. Leaves.


The black widow is found in pastures, stables, plains, mountains and fields, beneath rocks – and beneath the dry stems of wheat and plants. However, in many cases, residential buildings, especially cool and humid warehouses, can also be found.

Symptoms of Black Widow Bite

Other symptoms of spider bites include vomiting, shingles, respiratory and renal disorders, sweating, excessive fatigue, abdominal pain, paralysis, or general anesthesia.

If the spider is bitten and bitten, the first thing to do to save the poisoned person is to rinse the site with a disinfectant so that the infection does not spread. The person bitten by the spider may not notice it immediately and the bites will be painful over time, and the bite will be swollen and swollen and will have severe pain after 1–5 minutes. Then wash the wound with soap and water and place an ice pack on the wound to prevent spider venom from spreading. But before the patient gets poisoned, you need to get the patient to the first medical center. Fortunately, the spider’s antidote is produced in Iran and most medical centers in high-risk areas have access to it.

Choose a widow’s name for this spider

The female is named after this male spider after killing its male partner.

This is done after laying for two reasons:

6: Because she becomes very hungry after pregnancy

2: To transfer the gene or DNA from the male to its offspring, consider its partner as a prey.
