Crossopriza lyoni are not spiders at all, but rather belong to a totally different species called Opiliones. These creatures lack two features that would make them actual spiders: They cannot spin webs, and they do not have fangs to inject venom.

Even though Crossopriza lyoni is not a spider, it is still considered to be a cellar spider along with the Pholcus phalangioides. This is because both species swarm and cluster in dark, dank and moist man-made structures. Both species are synanthropic, which means that they prefer to live within or in close proximity to human dwellings.

The Crossopriza lyoni hatchlings will become a full-grown daddy longlegs in 80 days. These daddy longlegs species can live from 6 months to 2 years. Pholcus phalangioides eggs take 9 days to hatch, and they can live up to 3 years.
