He was censor in 102 BC with his cousin, Quintus Caecilius Metellus Numidicus.
The Caecilii Metelli were an extremely prominent family in the late Roman Republic.
Caprarius was the youngest son of Quintus Caecilius Metellus Macedonicus.

Balearicus was given the command to defeat the inhabitants of the Balearic Islands, who practiced piracy.
The other married Publius Cornelius Scipio Nasica Serapio, who was consul in 111 BC.
Creticus was given the proconsular command against the island of Crete, which was aiding Mithridates and infested with pirates.
Caprarius was censor in 102 BC with his cousin, Quintus Caecilius Metellus Numidicus.
In their censorship, Numidicus tried unsuccessfully to expel Lucius Appuleius Saturninus and Gaius Servilius Glaucia from the Senate.
He proposed a law to reduce grain prices that received the support of Glaucia.
They used violence in an attempt to reach their goal, and Saturninus murdered Glaucia's competitor for the consulship.
To get revenge for the attempted expulsion from the Senate, Saturninus tried to force Numidicus to swear acceptance of a law that gave land to Marius' veterans.
