Citywide Fly Diversity Patterns
UNRC entomologists Dr. Brian Brown and Emily Hartop have reported on patterns they've discovered from a year of BioSCAN fly samples collected across Los Angeles. They identified 99 species of flies in the family Phoridae from the traps, after sorting and examining 42,480 specimens. They found that five species were collected at all sites, but that the entire fauna was dominated by a common fungus-feeding fly, Megaselia agarici, which made up a quarter of the entire catch. Other fungus-feeding species were also abundant, and flies with this life history made up 40% of all phorid flies collected. The map shows the BioSCAN trap sites, with red circles indicating high diversity and blue low diversity.
