Skreed

In his book, the coming of Tan, Riley Martin describes how he was taken on board of a huge egg-shaped "mothership" in the vicinity of Saturn. On the mother-ship he learned it was inhabited by seven different species of intelligent technological life forms, of which the Skreed, or Insectillians, are one.
Riley descbribes them as five foot tall insect-like creatures with super intelligence. Riley often refers to them as 'smart bugs.'

No other authors mention this species.
