So they do make a web and they Do have venom the common assumption is that they eat other spiders that are more venomous that they so therefor must have very potent venom this ofcourse is wrong it's their speed that allows them to capture and eat other more poisonous spiders
Looks like we are talking about different things. I thought that daddy long leg is the common harvestman, which is not even a real spider
The harvestman does not bite with venom nor does he make web.
