Bugs thrive in urban Los Angeles – volunteers’ traps reveal biodiversity hot spots for city insects and spiders
City life can mean lots of pavement and habitat loss. But many bug species are hanging on, especially in neighborhoods with steady temperatures near the mountains.
The most significant predictors of bug biodiversity in Los Angeles are proximity to the mountains and temperature stability throughout the year, according to a study we co-authored with Brian V. Brown of the Natural History Museum of Los Angeles County and colleagues at the University of Southern California and California State University.
The project used data from the museum’s BioSCAN project, where volunteers across Los Angeles allowed insect traps to be installed on their property between 2014 and 2018.
