Toxic to Animals

Triangle crab spider has a toxicity that is generally considered mild. This species employs its fangs to deliver venom, which can affect both warm-blooded and cold-blooded animals. When bitten, a human or a dog might experience localized pain or swelling as the venom is not potent enough to cause severe harm. Smaller creatures, like flies and bees, are more likely to suffer more serious consequences, if not fatal, due to their smaller body mass and different physiological responses to the toxin injected during a bite.

Rectangle
Bite Humans

Triangle crab spider is not characterized by biting humans. It typically does not display aggression towards humans and instances of biting are highly unusual and not part of its habitual behavior. Encounters leading to bites are rare and often a result of self-defense or unintentional contact, rather than predatory instincts. Direct consequences of such accidental bites are generally mild.
