Could you ID these please?

[The Snark]

This is our version of the 'banana' pidey I think. Her leg span, front to back, is about 8 inches. Average for around here. The male there must feel a little intimidated. This one is an orb weaver of course.

I have no idea what this one is. Her body is about an inch long. This one seems to have spun a web similar to a therididae (I think)

Hi,

just two quick ideas:

1. Nephila spec.
2. Argiope spec.

[Stylopidae]

I don't know about agriope, stefan. Snarky did say that it spun a sort of cobweb type thing, don't agriopes spin orb webs?

Unless therididae aren't cobweb spiders :?

Still learning

 

[ta2edpop]

First one is a tetrgnatha elongata. I believe.

 

[ta2edpop]

The second one looks like a marble orb weaver araneus marmoreus. I think.

I agree with Stefan, though I have no personal experience of these genera.

Hi NRF,

thanks for that.

Now there are two people agreeing about the ID-idea, that both haven´t any experience with such spiders....

... quite funny to me.

Hey, man...I'm just saying that if it doesn't spin an orb web, then it isn't an orb weaver. That's my understanding.

I never said you were wrong, just asked why you thought it was an agriope even though it didn't spin the characteristic web.

I even said I was still learning about the whole ID thing.

Second that.

There are usually exceptions to any rule especially when it comes to evolution.
I grew up in northern MN and the shamrock an/or related species up there often weave irregular webs. Sometimes you'll find one up high with what looks like a drunkin attempt at an orb web, but mostly ones that resemble a web of a comb-foot.

The second spider. I have only seen two of them and they were both clinging to or next to a wall with very little web. I'm not sure what is going on as I was given the impression, by the critters appearance, that it is an orb weaver. I need to investigate further.
So the concensus is, if it is an orb weaver it is possibly araneus marmoreus. If no indication of an orb web, an argiope?

Hi,

I'm not sure about the genus of the second one but the habitus is rather typical for an Araneid orb weaver, and it has some similarities with Argiope. That's probably why we say we think it is an Argiope. I have only seen pictures of Argiope and Nephila (we have neither in FIN). But there should be no doubt that the first is an Nephila and that second one belongs in Araneidae. May be it just had no orbweb at the time it was found. Some species only spins web during night, which will soon be destroyed by wind and rattling insects.

For most Araneids it is not necessary to know the web to be able to place the spider in right family or genus, but it is not always easy to tell the carachteristics why we think it looks like, in this case, Argiope. Its just the overall habitus.

I cannot see any pics of webs, only some threads or the hub of the web. The web page does not convince me when their shamrock spider Araneus trifolium is represented by pictures of at least four! species: A. diadematus, A. marmoreus, A. trifolium and a fourth to me unknown ?Araneus...

 

[The Snark]

Well I owe everyone an apology. I am ashamed I didn't do my proper research work. I spotted her, #2, when I was shooting the tetra and fell in love. I'll drag my hiney back up there and do the research.
But all you arach fanatics, come on! When you spot one that large and beautiful, we tend to loose our heads sometimes, right? :drool: :} :drool: :}

I second (or third) this.
