They are generally much smaller and more delicate, too. Similar species: Long-legged cellar spiders (in the spider family Pholcidae) are sometimes called “daddy longlegs,” but they are definitely spiders: They weave cluttered, irregular webs in the upper corners of basements, caves, and similar places and clearly have two distinct body regions: an oval abdomen plus a rounded head.
Sometimes there are tiny yellow, orange, or red blobs stuck on the body or legs: These are mites parasitizing the harvestman. Their chelicerae (mouthparts) are too small to bite people. They lack venom, but they emit a weird odor when disturbed. These spiders not only possess unique physical traits but also play important roles in various ecosystems. Lacking silk glands, they never build webs. Body length: 7-10mm Conservation status Common When to see All year round. They also lack silk and venom glands, and they only have two eyes. The body is a simple oval, and it’s usually hard to tell where the “head” ends and the segmented “abdomen” begins. We can easily see differences between harvestmen and spiders.
Most of us are familiar with the common, harmless, spiderlike “harvestman,” with its remarkably long, wiggly legs. Sometimes called the Daddy Long-legs Spider it is relatively easy to identify due to the very long legs and cylindrical body.
