I was so shocked to find out clavipes wasn’t native either. Joros fair better in colder weather it seems so I’m excited to see them around my place in the future

I didn’t know the genus was spread so widely in this hemisphere. I’ve only seen one so far and that was in S America. The webbing was gorgoeus gold.
I know they are in NY- how much etc unsure
The only thing I wonder about is do will they outcompete natives for food.

Looks like a non native Argiope almost , I still haven’t seen one here. Yeah I’m not afraid of spiders , but they assume the reader is panicking …🫠

Trichonephila in general? I’ve seen clavipes in North Carolina, and South Carolina, as well as Florida, they are everywhere. I’ve found joros about 2 hours away in South Carolina but they’ve been spotted a few times in North Carolina near me but I haven’t found them yet

Thanks for that data sheet.
Out compete. Jury is going to be out on that for quite a while. Clavata is still adapting.
Of great concern to me is the use of pesticides. With pressure washer and powered backpack sprayers recently making the scene here the genus is definitely in decline in nearly all rice growing areas.

pesticides wiped out most spiders and bugs here they have a potential for mass extinctions. 🥲

I'm hoping they are able to establish themselves in rural areas where pesticide use is strongly regulated. They could be wonderful goodwill ambassadors helping people get used to huge but harmless and very beautiful spiders. They can be forced into threat poses and deliver a painful but not considered medically significant bite.
I have my doubts that they actually have birds on the menu. Most likely birds occasionally get trapped in their webs but I suspect they would simply ignore, cut away that section of web, or even abandon the web. I can't imagine the heftiest female nipping and webbing a bird into a meal. Very hard to just deliver enough bites through the feathers.

Trichonephila clavata will likely compete with local Argiope species but who knows who will outcompete whom it all comes down to environmental conditions, and behavioural advantages specific to the species.

Argiope species are known to get pissed off and bounce around in the center of there web .
That’s a competition.

I don’t know, I went hiking the other week and found Trichonephila clavipes and Argiope aurantia at the same park but both lived in distinct sections. The clavipes lived in the more forested section and the Argiope lived in the more scrubland/meadow ish section

Maybe there is hope. The difference between Introduced vs invasive, let's go!!!

That's been the general rule with my observation so far. Nephs prefer higher locations which don't restrict their web building. Guy lines of >5 feet are common.

Oh yeah, they need those tall trees. My favorite thing to do is take an hour or so trip to see them. I love their population density and how massive their webs are. It’s just so cool to see in person. The first T. clavipes I ever found was an adult female with support lines stretching more than 10 feet high. It was amazing to see

@Biollantefan54 The most amazing one I've seen was suspended from telephone lines about 30 feet up with one guy line attached at the base of a phone pole and the opposite perimeter guy attached to a foot tall weed 9 paces, about 28-29 feet away from the base of that pole. The orb itself was about normal, a little under 3 feet across.

I’ve seen regular weavers do something similar up in tall telephone poles up were moths fly with lights around but never did I see a 28 foot web base, 10 foot Ive seen I still have dreams of hunting orb weavers . With moths flying around I loved chasing big moths but there gone now here.

8 to 10 feet seems to be about the limit for the big kids, argiopes and marbled. What they really like is to be among flowering plants. A mature pruned rose garden is heaven for them.

Well this sure looks like one of them to me, & if it is, I've got news for them...they've moved pretty far north, because my Mom found this one in her garden, & sent me these pics. She lives in a suburb of Buffalo, NY...
...if this isn't one, I'm assuming it's a relative...yes?
