Druden

Druden were a race of insectoids.

Biology
Druden were green, had long antennas, black eyes and yellow pincers on their mandibles.

Druden were carnivores and could survive eating deceased human flesh. Young Druden especially needed to be fed quickly in order to survive. Young Druden were referred to as Sucklings. (DWAN: Plague World)

History
Some Druden invaded the planet Publius and hid in a lair in the Forbidden Valley on the planet. They sought to spread a plague on the entire population so the humans would die and they could feed the corpses to their young. The Fourth Doctor and Kidson stopped them with Kidson sacrificing himself by crashing his Starto-Cruiser into their lair which exploded and caused all the rocks to cave in and kill them.
