The presence of 30 new fly species has been confirmed by researchers in urban Los Angeles after analyzing the results of a thorough survey of the sprawling city's environs. Researchers with the Natural History Museum of Los Angeles County carried out the so-called BioSCAN project.
Help to conduct the survey was also sought from local residents who hosted insect traps in their backyards. A microclimate weather station that monitored localized conditions was fitted in each trap. The researchers regularly emptied the traps and conducted studies on the insects.
