Is the Daddy Longlegs Spider the most poisonous in the world?
There is a site out there that says that daddy long leg spiders are the most poisonous spider in all the world, but its fangs are too small to bite humans. There are several species of arachnid that are referred to as “Daddy Long Legs” so this statement is a little misleading. Not all of the species called daddy long legs even have poison glands. (Which means that no, they won’t bite you, if they don’t have poison glands.) No studies have been found by all the people on the internet looking up this very same question, on the toxicity of the poison produced by those “daddy long legs” who do have poison glands, but everybody seems to agree that “most poisonous” is probably overstating the case. This site: http://www.urbanlegends.com/animals/daddy_long_legs_poisonous.html addresses this question as does http://www.straightdope.com/mailbag/mdaddy.html, which agrees. Roy Crawford, the Curator of Arachnids at the Burke Museum in Washington, tackles this same subject on his spiders myths page
