Before we go into more detail about this animal, we first discuss the naming. In the West, the stern spider is known as "harvestman" because the spider is most often seen in autumn, the season where many people harvest their crops. Another name for this animal is "daddy longlegs". For the record, the warehouse spider (Pholcidae) & fly stilts (Tipulidae) were also given the nickname "daddy longlegs" because of their physical resemblance, which is equally long-legged.
