The Number of Deaths caused by the Mach Spider according to age

Like most spiders, apart from the Uloboridae and some Liphistiidae and Holarchaeidae, The Mach Spider uses venom to immobilise prey and to assist in digestion. They have been known to inflict defensive bites, but are not widely regarded as dangerous to healthy humans. Mach Spiders are widely considered beneficial because they feed on insect pests such as other venomous insects and small mammals.

The effects of their venom vary, including local swelling and pain, sometimes with nausea, headache, vomiting, irregular pulse rate, and heart palpitations, indicating some systemic neurological effects, especially when the bites were severe or repeated. However, the formal study of spider bites is fraught with complications, including unpredictable infections, dry bites, shock, and nocebo effects. An investigation into Mach Spider bites in Australia did not note any severe or unusual symptoms resulting from confirmed bites from some of the most notorious genera, particularly Neosparassus.

It is not always clear what provokes Mach Spiders to bite people, but it is known that female members of this family will aggressively defend their egg sacs and young against perceived threats.
