2.Shaliman Black Widow.

3.Chariman tarantula.

4.Blue Star Tarantula.

5.Australian Tiger.

6.Super Black Widow.

7.Peat Bird Dancer - Produced in Indonesia.

8.Tiger spiders. Spiders can be broadly divided into web-forming spiders and wandering spiders by living and predating.

The most important characteristic of a web-forming spider is its web-forming behavior. Spiders secrete mucus through protrusions at the tips of silk sacs, which can congagulate into very thin filaments when exposed to air. Webs made of silk are highly sticky and are the main means of predation for spiders.

For insects that stick to the net, spiders will first inject a special liquid jujube digestive enzyme into the prey. This digestive enzyme causes insects to stun, convuls, and die, and liquefies their bodies, which feed spiders by sucking. Spiders are oviparous, and most male spiders are devoured by female spiders after mating with female spiders, becoming food for female spiders.

Loitering spiders, on the other hand, do not build webs, but wander around or camouflage in place to hunt prey, such as the tall spider, which is commonly known in Taiwan (worm na) (worm forehead).

So, there are many kinds, there are no diagrams.

Simply go to the Four Pests Pharmacy to buy drugs to kill spiders, and the root must be controlled.

Spiders that can't weave a web include bird catcher spiders, ant spiders, crab spiders, flower crab spiders, ant spiders, etc.

1. Bird catcher spider.

Although it does not weave webs, after catching its prey, the birdcatcher spider will use spider silk to treat a layer of webs on the ground as a carpet to ensure the cleanliness of the food, and then you can put the food on it and enjoy it slowly. ‍‍

2. Ant spiders.

The ant spider is a hunting spider, it does not weave webs, and its appearance and stature are very similar to those of large ants. If it mixes in with the ranks of large ants, it will be difficult for people to distinguish it. Usually it roams around, preying on other small insects like a hungry tiger.

When the weather began to get cold and prey was hard to find, it relied on this delicate camouflage that made it difficult to distinguish between real and fake, and blended into the heavily guarded ant nest.

3. Crab spiders. Because crab spiders can't weave webs, spiders that can't weave webs are called crab spiders. Crab spider is a spider that does not weave webs, only waiting for the prey to run close to it to catch it, and it walks sideways, a bit like a crab, so it is called a crab spider.

This spider does not use a web to hunt for food, its predation method is to lie in ambush behind the flower and wait for the prey to pass by, and then go up and stab it lightly in the neck, you don't underestimate this light stab, which can kill its prey.

4. Flower crab spider.

The flower crab spider is a spider that does not weave webs and likes to prey on bees and is not venomous. Their patterns are relatively unique, and they walk sideways, a bit like crabs, so they are called crab spiders.

5. Nomadic spiders.

Cave hunting spiders do not weave webs, and when they move, they drag a filament around and feed on their backs.

If some spiders look like they have hair follicles on their tails, then they are poisonous and it is best not to touch them, and if there are no hair follicles then they are non-venomous.

Generally, in the environment we live in, we rarely encounter poisonous spiders, generally poisonous spiders are very bright in color, the more bright the color, the greater the toxicity, non-poisonous spiders do not have fangs, and poisonous spiders, there are obvious fangs and venom glands.

Generally speaking, ordinary black spiders are not poisonous, and brightly colored spiders are.
