Tektonargus is a trace fossil ichnotaxon genus of insect, from the Late Jurassic period. It was discovered in a section of the Morrison Formation, located in Colorado, western North America. The name Tektonargus comes from the Greek word tēkton meaning artisan/craftsman and the Greek word argus referring to the mythological giant Argus Panoptes, who was all-seeing. It appears to have been created by a caddisfly.
