The Fireflies was a firemen unit of Starling City Fire Department.
The Fireflies was a firemen unit who had distinguished themselves by tattooing a picture of firefly on their hands.
In 2009, a member of the crew, Garfield Lynns, seemingly died in a fire at the Nodell Towers. After the station house was shut down sometime after 2009, members of the unit went to different companies.
In early 2013 it turned out that Garfield Lynns survived as he went on a killing and arson spree, murdering three ex-members of the group, including Danny de la Vega. He later tried to kill a handful of firemen at the fundraiser in Oliver Queen's club, mainly targeting another ex-Firefly, Raynes, now a fire chief. The latter was saved by The Hood, who confronted Lynns.
