Arachnophagy (/əˈræknɒfədʒi/, from Greek ἀράχνη aráchnē, 'spider', and φαγεῖν phagein, 'to eat'), also known as araneophagy, describes a feeding behaviour that involves eating arachnids, a class of eight-legged arthropods that includes spiders and many other species groups including scorpions, ticks, and mites. Aside from arachnophagy by non-human creatures, the term can also refer to the practice of eating arachnids among humans.^[1]

Arachnophagy is widespread among many animals, especially reptiles and birds. For example, arachnophagy is described among Philippine scops owls that feed on spider species such as Heteropoda venatoria.^[2]

Spiders are also eaten by many other types of animal,^[3] and spiders themselves can eat other spiders, including those of their own species, most commonly in acts of sexual cannibalism.^[4]

Like the human consumption of insects (anthropo-entomophagy), arachnids as well as myriapods also have a history of traditional consumption, either as food or medicine. Arachnids include spiders, scorpions and mites (including ticks) that are consumed by humans worldwide.^[5]

Fried spider, primarily tarantula species, is a regional snack in Cambodia. In Mexico, tarantula have been offered in tacos, with a splash of guacamole.^[6] However, Mexican law forbids the sale of many species of tarantula for human consumption, and vendors offering this delicacy have been shut down by authorities.^[7] In Venezuela, the Piaroa people have a history of eating the Goliath birdeater tarantula (Theraphosa blondi).^[8]

Fried scorpion is traditionally eaten in Shandong, China.^[9] Other countries include Vietnam and Thailand.^[8]

Milbenkäse is a German speciality cheese that is exposed to cheese mites during ripening, and on consumption often still has mites attached to the rind.^[10]
