Spiky, Hairy, Shiny: Insects of L.A.

If we want to understand how our decisions shape the world around us, we can start by simply paying attention to what insects are doing in our own neighborhoods.

On any given day in L.A., count on running into thousands of insects, many of which are barely visible. Since 2012, volunteers and Museum scientists have been collecting and photographing samples of this diversity as part of the BioSCAN (Biodiversity Science: City and Nature) project—in the process documenting environmental change over time. Spiky, Hairy, Shiny, an online exhibition, zooms in on this hidden world: come meet these six-legged Angelenos and let their beauty surprise and delight!

The "tail" of the snakefly (Agulla sp.) is actually an ovipositor, a specialized body part used by females to lay eggs. Specimen length: 13 mm

Tachinid fly microscopic image with a life-size pinned specimen on the left

Soothing Sounds

When you have a quiet moment, put on your headphones and be transported via the sounds of Los Angeles insects, from dawn to dusk.

BioSCAN: The World's Largest Urban Biodiversity Study

What makes BioSCAN the biggest survey of its kind? First of all, the number of insect traps (80) placed by Museum staff and volunteers. Second, the urban setting: the BioSCAN project is discovering new species and examining insect distributions in the core of the Los Angeles Basin and out to the coast, mountains, and nearby deserts. Through biodiversity studies like these, scientists can track which species are in an area and how common they are. To date, we have identified 800 species, including 47 species new to science. For more results, see here.

Malaise trap in garden for BioSCAN community project

We set up Malaise traps at sites across the L.A. Basin. Site hosts monitor the traps and remove the sample once a month.

Petri dishes with malaise trap samples

We bring the samples back to the Museum, where we process them and record the data.

Work-study student looking through microscope

Work-study students and volunteers sort the insects.

Entomologist looking at insect sample

After preliminary sorting, our entomologists identify the species.

Jars of insect specimens

We dry and label specimens; some go to collaborators at other institutions, but most stay in our collection.

Our ecologists analyze the data.

Finding Insects in Your Neighborhood

No matter where you live in Los Angeles, you can find—and support—native insect communities. Roll over a few of our BioSCAN collection sites on the map below to see examples.

Activities

Here are some things you can do at home (or just about anywhere) to observe and learn more about the insects around you.

The BioSCAN project was made possible in part through the generous support of Esther S.M. Chui-Chao and The Seaver Institute. The project also would not have happened without the collaboration of our BioSCAN site hosts, who provided access to their yards, community gardens, local green spaces, and schools. We are grateful for their cooperation and dedication.
