Backyard Bugs: LA’s Unsung Biodiversity
Sitting in gridlock watching wildfires burn in the distance, it’s easy to fall victim to the stereotype of Los Angeles as an apocalyptic wasteland. Freeways, parking lots, and stripmalls make it difficult to imagine LA as an ideal location for studying biodiversity. And yet somehow, in this collision of urban and natural environments, there are species that thrive. To understand this unique environment, the Natural History Museum (NHM) launched Biodiversity Science: City and Nature (BioSCAN), a research project exploring the insect biodiversity of Los Angeles.

On July 30, Obscura Society LA gathered at Center for the Arts Eagle Rock for an evening of six-legged exploration. This two-part event began with a lecture from BioSCAN and ended with a hands-on insect pinning workshop.

BioSCAN is a three-year research project that aims to examine the insect biodiversity of Los Angeles. Collecting weekly samples from 30 sites across the city, their goal is to identify and map species, and to understand how they are affected by urban development. BioSCAN entomologist Lisa Gonzalez described the project and revealed they had uncovered many new species. While their identity remains a secret until their debut in forthcoming publications, she did introduce us to some other charismatic creatures collected from the project whose roles ranged from cadaver decomposition to plant fertilization.

The Bumble Bee: While there are 26 species of bumble bees species in LA, this is the only individual collected so far. The BioSCAN team cites “commercial keeping of bumble bees, habitat loss, pollution, and climate change” as reasons for their decline. (photo by Phyllis Sun)
The Fig Wasp: Bound together in obligate mutualism, the fig wasp & the fig cannot survive without each other. (photo by Kelsey Bailey)
The Botfly: The appearance of this “furry teddy bear” in the collection sample triggered a Happy Fly Dance in the BioSCAN lab. This particular botfly, Cuterebra latifrons, requires the Dusky-footed wood rat to complete its lifecycle. (photo by Kelsey Bailey)

The insect pinning workshop was lead by Suzanne Berhow, an active member of the taxidermy world and an artist known for her carefully crafted and beautiful pinned insects. This hands-on experience allowed the Obscura Society an up-close look at a few local bugs including a Mourning Cloak butterfly, a Milbert’s Tortoiseshell butterfly, and several varieties of beetles and bees.

S the next time you’re feeling trapped in a concrete jungle, turn off the freeway and discover a secret world buzzing with metallic bees and furry flies. Thank you, Suzanne Berhow, Lisa Gonzalez, and the entire BioSCAN team for sharing LA’s beautiful, backyard bugs!
