Frequently Asked Questions

Behavior, Diet & Habits

Understanding Daddy Longlegs


  • Size: They measure 5/16 of an inch in length

  • Color: They are usually brown or grayish in color.

  • Body: Harvestmen have one body segment, two eyes, and eight legs. Their second pair of legs are longer than the others and function as their smell and taste sense organs.

Behavior & Diet

They have many names such as harvest spiders, shepherd spiders, and grandfather graybeards. Their proper common names are daddy longlegs, harvestmen, or opilionids. These organisms are called harvestmen because they are often seen in large numbers in the fall around harvest time. During the fall, their populations may briefly cluster together. Unlike spiders, they do not create silk webs.

Harvestmen primarily search for food at night. They use their mouthparts to hold their prey while they feed on them. In fact, these mouthparts are very similar to crabs. They produce a strong odor that repels most predators to use as protection.


Outdoors, harvestmen prefer to live in damp, shaded areas such as on trees, under eaves, and underneath logs and rocks. It is rare to see harvestmen in home living spaces. If they make their way indoors, they hide in areas including:

  • Basements

  • Crawlspaces

  • Garages

  • Sheds


In northern portions of their range, harvestmen live for only one year, while in the south they may live up to two years.
