In his book, the coming of Tan, Riley Martin (1946-2015) describes how he was taken on board of a huge egg-shaped "mothership" in the vicinity of Saturn. On the mothership he learned it was inhabited by seven different species of intelligent technological life forms, of which the Skreed, or Insectillians, are one.
Riley described them as five-foot-tall insect-like creatures with super intelligence. Riley often referred to them as 'smart bugs.'
No other authors mention this species. Many researchers question his credibility.
