Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
[1] [2] They are often distinguished from poisonous animals, which instead passively deliver their toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested. [1] [2] [3] The only difference between venomous animals and poisonous animals is how they deliver the toxins. [3]
Wasp stinger, with droplet of venom. A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous
Scorpions may be attacked by other arthropods like ants, spiders, solifugids and centipedes. Major predators include frogs, lizards, snakes, birds, and mammals. [78] Meerkats are somewhat specialized in preying on scorpions, biting off their stingers and being immune to their venom.
Many species of arthropods, principally insects but also mites, are agricultural and forest pests. [180] [181] The mite Varroa destructor has become the largest single problem faced by beekeepers worldwide. [182] Efforts to control arthropod pests by large-scale use of pesticides have caused long-term effects on human health and on biodiversity ...

Misumena vatia feed on common insects, often consuming prey much larger than themselves. They use venom to immobilize their prey, though they are harmless to humans. They face threats due to parasites and larger insects. For Misumena vatia, survival depends on the choice of hunting site. The spiders closely monitor multiple sites to see if ...
Symptoms of spider bites vary depending on the type of spider and if their venom is poisonous. Venomous spider bites can cause many side effects, according to the CDC , such as: High blood pressure.
