Meanwhile, here's another look at the Bohart Museum of Entomology's 2024 Moth Night, which drew widespread interest.
No one knows exactly how many moth events took place across the nation during National Moth Week, just as no one can predict how many species of moths and other night-flying insects will come to your porch light at night, or to your blacklighting display (UV light illuminating a hanging white sheet).
"Scientists estimate there are at minimum 150,000 moth species, and some believe that there could be over 500,000! Moths have been found that are small as a pinhead and as large as an adult-human's hand," according to NationalToday.com. "But of course, it's the incredibly complicated wing colors and patterns that make them especially dazzling."
A New Jersey non-profit organization, Friends of the East Brunswick Environmental Commission, launched the national event in 2012. The organization is dedicated to the conservation and promotion of the local environment.
The Bohart Museum's global collection of 8 million insects includes some 825,454 specimens of moths and butterflies, including 618,750 moths, ranging in size from the huge Atlas moths (10-inch wingspan) to the extremely tiny (4 mm wingspan) leafminer moths, says Jeff Smith, curator of the Lepidoptera collection. He and Bohart associate Greg Kareofelas showed dozens of moth specimens and answered questions.
What moths were drawn to the blacklighting display? (See list on Bug Squad blog). Retired UC Davis staff associate John "Moth Man" De Benedictus and his colleagues set up the blacklighting display. UC Davis doctoral student Iris Quayle fielded questions about the differences between moths and butterflies (See Bug Squad blog).

Light Pollution. The Coggans answered many questions about light pollution. "Most organisms have come to rely on nighttime darkness for knowing when to reproduce, preparing for the winter, and moving around their environment," commented UC Davis doctoral student Peter Coggan. "The Industrial Revolution Artificial Light At Night (ALAN) has become a major conservation issue, disorienting and confusing countless species, often resulting in death. ALAN often kills or displaces organisms like bats, moths, and fireflies, making our nights less bio- diverse and more mosquito filled."
"Not only does it alter animal behavior but ALAN also has been linked to many human health issues like depression, obesity, and cancer," he said. "Although not widely known, ALAN is one of the easiest environmental crises to solve. Raising awareness and getting communities to reduce their light usage can solve the issue overnight and bring back the animals of darkness and the stars back to them."
The Bohart Museum's Moth Night also featured a display of various silk textile and cocoons, donated to the museum by Professor Richard Peigler of the University of the Incarnate Word, San Antonio. Bohart associate Mike Pitcairn, retired senior environmental scientist and supervisor, California Department of Food and Agriculture's Biological Control Program, staffed the table.

The Bohart Museum, founded in 1946, is located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. Director of the insect museum is Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair of UC Davis Department of Entomology and Nematology, and associate dean, Agricultural Sciences, UC Davis College of Agricultural and Environmental Sciences.
The open houses are free and family friendly. The next open house is on Saturday, Sept. 28 from 1 to 4 p.m. The theme: "Museum ABC's: Arthropods, Bohart and Collecting." Access the website at https://bohart.ucdavis.edu or email bmuseum@ucdavis.edu for more information.
