Skithra

The Skithra were a species of scorpion-like beings. At least one individual, the Queen of the Skithra, had a partly humanoid appearance. As a hive species, if the Queen was destroyed, then the rest would die.

The Skithra were able to fire an energy resembling electricity from their stingers. This energy would appear green when being charged and would turn red when about to be fired.

The Skithra were scavengers and lacked the imagination to build something for themselves. They would steal the technology of other races and use it rather than building their own. Races that the Skithra have stolen from include the Silurians, Thassor, Venusians, Klendov, and Dullirians.

The Skithra Queen threatened the Earth with a stolen Venusian spaceship with a Klendov warp drive and a Dullirian resonator. At some point, they stole a Silurian blaster, presumably from one of the underground settlements the species hibernate in, which they used in an attempt to kidnap Nikola Tesla.
