Can I remove part of the web a daddy long legs has woven without harming them?
This spider has taken residence in a corner of one of the rooms, I'm not bothered by them but the web is getting a bit too big... can I just remove part of it to keep the size in check without causing harm to the spider?
Unlike spiders, Daddy Longlegs don't spin webs because they do not produce silk. Daddy Long Legs actually have only two eyes unlike spiders who have eight. Another difference is that Daddy Longlegs are not venomous. They do not have fangs or venom glands. - from Google.
There are many arachnids that shares the common name. Opiliones, or harvestmen, is what you are referring to. But a family of spider, phoclcidae or cellar spiders, spin webs and does whatever a spider does.
No, the daddy long legs you're talking about is a spider and of course it spins its webs. @PolyLlamaRous was talking about something completely different, the harvestman.
Some of the confusion over whether the daddy longlegs is a spider comes from the fact that there are two are small creatures with that name, and one actually is a spider.
The daddy longlegs spider is the cellar spider. It is pale gray or tan and has banding or chevron markings. Crane flies, which resemble large mosquitoes, are sometimes called daddy longlegs as well.
