Welcome to Opiliones Wiki[]

Opiliones is a collaborative website about harvestmen that anyone can edit!

Quoting (paraphrasing) Seiyapedia: Disappointed by the amount of erroneous data floating around on the web, and frustrated to see their contributions in constant jeopardy at Wikipedia, we decided to create our own organized hub of information.


The idea is to centralize knowledge on Opiliones in a single place which links to a wealth of information on the web and in the real world using the immense power of collective edition. It is only an embryo, but it may become something meaningful, depending on OUR input...


The easiest way to browse is to access the categories using the "browse" ultra category [1].

Our dear contributors are listed in the page of image sources for Opiliones Wiki [2].

NEW: List of the institutions that serve as repositories of type material, organized by country and city! [3]

Or else, jump straight to some of the main categories:
