Chiru
this species of insect was native to the planet Socorro, and was known for its vicious nature. Named with the Socorran word for "deadly," the chiru was known to live in colonies of more than 100,000 individuals. They were attracted to vibrations, such as that of a starhip repulsorlift engine, and would swarm an unsuspecting traveler who went out into the desert in an unmuffled landspeeder. Their lifecycle was punctuated by the intense seasons experienced on Socorro. When the planet plunged into deep winter, huge portions of the chiru population were killed in the cold. Those that survived came out of hibernation as summer approached. The increasing heat triggered their mating instinct, and within months the colonies were fully populated again.
