These are some the large true spiders. They are beautiful and not dangerous. They great for gardens and backyards for appearance sake and to lower mosquito and fly populations.
Look for large webs, sitting in the middle of them. Typical Orbweaver behavior. Females much larger than males.
Males are much smaller than the females.
In the Southern United States, look during the summer months, especially around June and July.
Desire to flee, not defensive.
I can not say for certain this is preferred environment, but the population I was studying was typically found near the river, while Trichonephila clavipes was more commonly found in the wooded areas among the trees, however, their were exceptions for both species.
They would be difficult to keep indoors because they require such a large space. Consider keeping them in your backyard only if they are native to where you live.
Find them or purchase online. They are very common, you maybe able to find them near where you live if you live in the Americas.
Price: $60 maybe
