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 ...
Workers deliver 0.66 nl of venom when they sting, which amounts to 3.1% of their supply. Older workers deliver less venom when they sting, but middle-aged workers and nest-defenders deliver much higher quantities. [13] Like all fire ant species, venom is secreted by the venom gland and is stored in the poison sac. [14]
Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting. [3]: 450 First aid for fire ant bites includes external treatments and oral medicines. [citation needed]
[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]
These ants release a complex venom mixture that can include histamine. Within the subfamily Formicinae, the stinger has been lost and instead the poison gland forcibly ejects the fluid of choice, formic acid. [8] Some carpenter ants (genus Camponotus) also have mandibular glands that extend throughout their bodies. When these are mechanically ...
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

Ant mimicry has a wide taxonomic range, including some 2000 species of terrestrial arthropods in more than 200 genera. It has evolved over 70 times, including some 15 clades of spiders, 10 clades of plant-sucking bugs, and 7 clades of staphylinid rove beetles. Outside the arthropods, ant mimics include snails, snakes, and flowering plants. [14 ...
