"meat honey"
The vulture bee is sometimes said to produce a so-called "meat honey", but this is a misnomer resulting from scientific uncertainty, due to historic confusion of multiple species, each with a slightly different method of processing.
In one detailed study of Trigona hypogea in Brazil, the vulture bees mixed sugary plant products with a proteinaceous paste from regurgitated meat, and let it mature to form a sweet substance that was used as food; however, the two resources were initially kept in separate "pots" in the colony, neither being true honey (i.e., not derived from nectar), but they were then mixed together.
In a different study of Trigona necrophaga in Panama, the bees gathered nectar and produced honey, and they also produced a glandular secretion, derived from carrion, partially metabolized, used as a protein source, and kept completely separate from the honey. In neither case were the bees mixing meat-based substances with floral-derived substances.
