Spider - what model is it?

I did not forget. Tiger is a casual with a cave spider. Meta Menardi - Anyway, he has already earned a Polish name - Jaskiniowy Net.
Tiger's toxin is delicate. The cave spider has a very blue venom because it is quite slow and would get away with anything. And when something works, it's 110% effective. Living in a cave and waiting for an opportunity, he can't afford to waste them. Evolution. The harder it is to hunt something, the more effective the hunter is.

In addition, the argiope is an invasive species from the south in Poland. Even 20-30 years ago, they were practically non-existent. Therefore, it is difficult to consider it "our" species.

Are.
If I'm not mistaken, 3 species of the gnat family. All small and quite rare. They do not hunt birds, because for them the cricket is a large prey. No less - as tarantulas...

As it has already been rightly noticed, gnats are NOT tarantulas.

There is only one spider in Poland that can cause something more serious in humans. And it is a cave spider from Ojców.

This is an urban myth. The venom of these spiders is completely harmless to humans.

The least venomous spider of Poland is probably Armored earring

Speaking of tiger Photos taken on a meadow near Olesno, province. Opole

It's not a myth. Ask speleologists. They often bite.
Secondly, don't confuse "most venomous" with "dangerous". It does not mean that the most venomous Polish spider has venom dangerous to humans. It's just that the effects of this venom are the strongest.

Echidna has quite a weak venom. The pain is the result of being bitten by exceptionally large fangs for a spider of this size. It's one thing to prick yourself with a pin, another to hammer a nail. There are also hemolysins.

It's the same as with the hornet venom myth, whose bite hurts the most, but not because of the venom, but because of the big stinger. This is where the little bee puts the hornet to shame when it comes to the dose and toxicity of the venom.

Evolution is practical. If an animal has one effective weapon, the other may not be as effective. For a slow netter, living in the dark and waiting for an accidental prey, there is no way for him to ambush the victim and make a successful attack and bite it. He has at most one chance to attack, and that chance must be effective. Hence, the venom has an increased toxicity. However, the victims of this spider are not vertebrates, and there are no enemies in this group. Thus its venom does not have to be unpleasant for us.

Echidna, on the other hand, lives in meadows and has powerful mouthparts. It is active during the day. Its venom doesn't have to be that toxic. However, it contains a substance that attacks the blood of vertebrates, which causes pain. This component of the venom serves to deter predators - one that gets bitten by one Echidna will not try to catch another.
However, it is not a dangerous substance, except for allergy sufferers. But for them everything is dangerous. :)

Therefore, the question is - do we judge by the perceived effects or by the actual toxicity of the venom?
Because it's not clear. Some toxins are downright pleasant to the bitten victim. But still deadly.

All information about the venom of this spider comes from the third or fourth hand.

Considering the forum we are discussing on, it can be assumed that when we say poisonous we are talking about the effect of this venom on humans.

This is simply not true. In every scientific article, it is described as one of the few European spiders that pose a certain threat to humans. Which, of course, does not mean that this spider kills people.

Again not true. The basic component of echidna venom is the peptide - CpTx 1, which has both insect-paralyzing and cytolytic (pain-causing) activity. However, you are right that size also matters as this spider is able to inject more venom and deeper into the body.

Since we're talking about Polish spiders, it's the same thing. Our spiders can only spoil our afternoon.

Help! I would like to know what I just saved at my son's insistence and is now growing in my garden...

@paulaosinska12 Scotophaeus.

Cute, reminds me of a Ferrari. :]
Once I had a beige one with a black pattern on the abdomen, skinny, maybe 1.5 cm long.
A smart guy, he made a cobweb almost parallel to the window pane. Flies flying to the light, of course, were often caught. Even so, I caught flies myself and threw them to him.
After 1-2 weeks of eating (I don't remember exactly), he grew into a huge cow.

Interestingly, every day he rolled up the web and unrolled it anew. The unfolding process was mesmerizing.



Don't kill - anyone can do that. Grab it in a glass and release it outside.

The worst is when some beast gets tangled with the dried laundry.

You catch it in a jar and release it outside.
They are by no means beasts. They may not be very cuddly, but they are not dangerous, but they are useful...

And someone who used to have arachnophobia told you that... ;)

I healed myself by reading a lot about these little ones - I wanted to know what they could do to me... And apart from a few cases, they can hardly do anything...

What's more, in their own way, they can be incredibly clever and certainly fascinating.

I hate when they walk on my sheets and face at night... Especially the big ones. No, I don't have arachnophobia.

I just found this spider

You're not the first. Post #10.

Stress the poor guy with some jar - you put your hand and he climbs on it and takes it to the garden, and on the way you can play with them so that he passes from hand to hand.
I've been evicting squatters to nature like this for years.
Some try to pick at the hair on their hands.
