Finding 30 New Species in Los Angeles Backyards
Posted by Richard Conniff on March 26, 2015
A team of researchers in Los Angeles has just described 30 new species discovered during a three-month study in ordinary backyards. Emily Hartop, who did much of the biological grunt work, has written a nice description of the project, and what it means:
When I came to work at the Natural History Museum of Los Angeles County, I had no idea exactly what was in store for me. The NHM had recently initiated a massive study to search for biodiversity, or the variety of life forms in a particular area. This study wasn’t taking place in some lush tropical jungle, though; in fact, far from it. This fabulous study was (and is) taking place in the backyards of Los Angeles. I got hired to be part of the entomological team for this urban project called BioSCAN (Biodiversity Science: City and Nature) and before I knew it, I was describing 30 new species of flies collected right here in the City of Angels.
Before I explain how this all happened, let’s pause and say that again: 30 new species of flies were described from urban Los Angeles in 2015. Let’s expand: these flies were caught in three months of sampling and are all in the same genus. What does this mean for us? It means that even in the very areas where we live and work,
our biodiversity is critically understudied. It means that in your own backyard, or community park, live species that we do not even know exist. It means that all of those invisible ecosystem processes that occur all around us are being conducted, in part, by creatures we know nothing of. It means BioSCAN is off to a good start, but we have a lot of work to do.
My boss, NHM Curator of Entomology Dr. Brian Brown, has spent years working on an amazing group of flies called phorids. When I started in January 2014, I knew next to nothing about phorids; I knew they were small flies that did some cool things (like decapitating ants and killing bees and eating cadavers in coffins) and that was about it. When I came in to volunteer my time prior to my official start date, Brian sat me down with some samples from Costa Rican rice paddies and asked me to pull out all the phorids for further study. I only vaguely knew what a phorid even looked like, so I had a steep learning curve that first day. Soon, though, I could recognize a phorid as easily as picking out an orange in a bunch of apples
