Daddy long legs just spit web everywhere and make a mess. I think replacing their bullshit with a more visually appealing and structurally sound fake web would be cooler for them.
Depends on where you are and what is referred to as a daddy long legs. The ones in the Midwest and northeast certainly don't have web makers or even fangs that could harm a human. Just weird little reddish-brown balls with Tron legs. The ones here in the southwest are clearish-yellow-white, and certainly spin messy webs with no structure. The one in Australia will kill you because, of course they will.
