Hexagoran
From Tardis Wiki, the free Doctor Who reference
The Hexagorans were an insectoid species.
They had the ability to be unnoticed by other species. A group of Hexagorans visited and surveyed Earth during the 16th century. After that, they settled on the planet Luparis. They built the capital city of Lupara to resemble Tudor London. (AUDIO: Hexagora)
