Rainbow suspected it may have needed to be placed in a genus separate to Atrax at the time, but demurred due to the lack of male specimens.

[7] A high proportion of bites—five out of eight recorded cases—from the northern tree-dwelling funnel-web spider result in severe symptoms of envenomation.

Applying pressure bandages and immobilising the patient can significantly delay the onset of symptoms and remains a critical part of the management of an Australian funnel-web spider bite.

Common symptoms include diaphoresis, hypertension, sinus tachycardia, muscle spasm or fasciculation, nausea and vomiting, altered consciousness and local pain at the bite site.

It lives in rotting logs, branches and hollow furrows and pipes of trees, particularly tallowwood (Eucalyptus microcorys), as well as in epiphytes.

[6] The arboreal habitat suggests that wood-boring beetles are a main prey item of the northern tree-dwelling funnel-web spider.
