Who Will Find the First Bumble Bee of the Year?
Bohart Museum Sponsoring 6th Annual Contest
Who will find and photograph the first bumble bee of the year?
The sixth annual Robbin Thorp Memorial First-Bumble Bee-of-the-Year Contest will begin at 12:01, Jan. 1, 2026. The first person to photograph or video a bumble bee in the two-county area of Solano and Yolo and send to the Bohart Museum of Entomology at [email protected] will win a coffee cup designed with the endangered Franklin's bumble bee, the bee that Thorp monitored on the California-Oregon border for decades.
The entries must include the time, date and place.
The contest, launched in 2021, memorializes Professor Thorp (1933-2019), a global authority on bees and a UC Davis distinguished emeritus professor of entomology, who died June 7, 2019 at age 85. A 30-year member of the UC Davis faculty, he retired in 1994 but continued working until several weeks before his death. Every year he looked forward to seeing the first bumble bee in the area.
The black-tailed bumble bee, Bombus melanopygus, is usually the first bumble bee to emerge in this area, Thorp used to say. It forages on manzanitas, wild lilacs, wild buckwheats, lupines, penstemons, clovers, and sages, among others.
The 2025 Robbin Thorp Bumble Bee Memorial Contest was won by Michael Kwong of Sacramento and Kaylen Teves of Vallejo, Monarch Watch volunteers who photographed a yellow-faced bumble bee (Bombus vosnesenskii) on an oak leaf at the Glen Cove Marina, Vallejo on Jan. 11 while they were looking for monarchs. At the time, Teves was a computer science student at San Francisco State University, and Kwong, a senior environmental scientist with the State of California.
