Certainly order Trichoptera, and with ocelli ('eye spots') on the head, 5 segmented maxillary palpi with terminal segment not flexible, and given size of 5 to 12 mm, probably family Hydrobiosidae. Larvae in this family are predatory and don't build cases until ready to pupate, when they build cases using coarse sand grains, usually under stones or in crevices in rocks. Very nice image.
Hi @Frecko these look to be all worker termites. For any hope of photo ID, soldiers are needed. Some people can ID workers, but I think you need dead ones and a microscope.
