Public domain "Orthopteroidea s.l." images by Arp (CC0)
Unsorted index to (most?) images of "Orthopteroidea s.l." (old style including Dermaptera, Blattodea and Mantodea) uploaded to this site by Arp.
All carry a Creative Commons "Zero" (CC0) public domain dedication, you can use them as you please without any licensing requirements or author attribution, as I prefer usage not to be hindered by any incompatibilities between all sorts of various (not so) "free" licensing schemes(!)
