Flaked blood fleas were a type of flea insect lifeform that were considered as a foodstuff on Ferenginar. (New Worlds, New Civilizations short story: "A Dry Day on Ferenginar")
The Federation Travel Guide recommended having flaked blood fleas in The 214th Rule restaurant on Ferenginar. (ST reference: Federation Travel Guide)
In 2370, Zek and Rom ate flaked blood fleas in Quark's. Zek found them surprisingly succulent and Rom suggested that Quark try them. (DS9 episode: "Rules of Acquisition")
- Presumably, these creatures were named because finding them or attracting them could involve dried blood.
