The Entomology collection holds over 900,000 labeled specimens, primarily of insects and arachnids, with small holdings of various other terrestrial invertebrate specimens. The collection is especially strong in Coleoptera (Beetles) and Lepidoptera (Butterflies/Moths), with smaller but important holdings of Diptera (Flies) and Neuroptera (Lacewings). Material is representative of San Diego County and Southern California, with additional specimens from the southwestern United States.

Of additional interest are the collections from northwestern Mexico, primarily Baja California, that have been added over much of the past 60 years. A smaller specialized collection containing insects of forensic importance is also available. Read more about the collection.

The Entomology Department is supported in part by the John A. Comstock Entomology Fund, and donations from The Sahan Daywi Foundation.

The department is under the care of Dr. Michael Wall, Curator of Entomology, with assistance from departmental associates. Dr. Wall joined the Museum’s staff January 20, 2006.
