Citizen Science

Los Angeles is a diverse, dynamic, ever-changing city, both for people and the wildlife that live here. Although we are frequently aware of the larger wildlife around us, like parrots and squirrels, many of the smaller animals remain unnoticed and even undescribed by scientists.

In order to understand our city better, the Museum has begun a long-term biodiversity study of urban habitats and surrounding natural areas. Our goal is to not only increase our knowledge of local wildlife, but also to involve our local community in this study.  From lizards to ladybugs, we need your help in each of our community science projects — the Museum can't do it alone!




In 2012, the Natural History Museum of Los Angeles County launched a new research initiative: NHM Biodiversity Science: City and Nature (NHM BioSCAN). This first-of-its-kind scientific investigation will discover and explore biodiversity in and around one of the world’s largest cities: Los Angeles.

Spider Survey

L.A. is an important international port, new species of spiders are always being accidentally introduced, and some are establishing breeding populations.  We need your help to find out what spiders are becoming established so we can understand what impacts they may be having on our native spiders.

Lost Ladybug Project

Partnering with Cornell's Lost Ladybug Project, the Museum hopes to census the ladybugs found in our region.  We have historic data of ladybug species in Los Angeles County, but we don't know how much it has changed — we need your help to find out.
