Colicoids were a sentient insectoid species from Colla IV.

In appearance, Colicoids were tall insectoid beings that held multiple appendages. Their bodies were chitinous and included a powerful stinging tail. A Colicoid’s physiology allowed them to curl up into a protective ball and unfurl suddenly which allowed them to catch their prey unaware. This rolling method of locomotion was described as being second nature to the Colicoids. They had flat heads with multifaceted eyes that provided them with a superior level of vision and their long antennae gave them an acute sense of smell. An average adult Colicoid measured between 1.8 meters to 2 meters tall. A number of cousin species of the Colicoids were developed with the aid of the Balmorrans. These mutants were shown to be able to metabolize the toxic waste of the planet and made unpredictable though excellent living weapons.

Some members of these insectoids were Colicoid Queens that were different than normal members as they were more than twice the size of even the largest warrior breeds. This made them extremely dangerous and were the only Colicoids that possessed a unique poisonous stinger. This combined with their strength and size made them deadly combatants, especially when within their nests. However, a Queen tended to only fight when her young were being threatened.

Colicoid lifespan allowed them to live to over 65 years of age. Children ranged between 1 to 4 years of age while a young adult was between 5 to 7 years old. They reached adulthood by 8 years old where they remained in this part of their lifespan until 33 years of age. They reached middle age around 34 to 49 years of age whilst an old Colicoid was between 50 to 64 years. A Colicoid was considered of venerable age from 65 years and over.

They were carnivorous, and sometimes cannibalistic. Colicoids wishing to protect themselves were capable of forming themselves into a tight ball, an ability the Colicoids emulated when designing the droideka, which they produced in their image. The only known predator of Colicoids was the hueche, which was so feared that the sight of one would cause any Colicoid to reflexively form itself into a ball and roll away. This fear was such a deeply ingrained instinct that it remained even after hueches were apparently driven to extinction, and even a holographic projection of a hueche would have the same effect on a Colicoid.

The insectoid minds of the species provided them a natural defense against mind tricks. There were no known Force users amongst the Colicoids.
