World Bee Day 2025

May 20, 2025

May 20th is World Bee Day, established by the UN in 2017 to bring attention to the importance of bee pollination for our food supply, and the concern that many bees are experiencing population declines. 

Do you want to do something to help save the bees?  Elizabeth Elle鈥檚 lab in Biological Sciences at 大象传媒 has shown that urban and suburban backyards can be important reservoirs of pollinator biodiversity.  Gardens can compensate for habitat loss by providing food (flowers!) for bees.  Her lab documented the endangered Western bumble bee visiting lavender in a garden (photo upper left).  Related plants in the mint family (catmint, thyme, oregano) are also pollinator magnets.  Other plants that are great for bees are 鈥渆asy access鈥, like the members of the sunflower, and rose families shown in the photos.  Elizabeth is currently working with gardeners to understand how gardening practices, such as leaving nesting resources from stems to the rocky path in the bottom centre photo, can support bees in your backyard.

Melissodes microsticta male on Rudbeckia - A male small long-horned bee sips nectar on a black-eyed Susan flower. The 鈥渓ong-horned鈥 portion of their name refers to the distinctive long antennae which males have.

Anthidium manicatum female 鈥 A female European wool carder bee rests on a rock. This species of bee was introduced to North America in the mid-20th century. They are called wool carder bees because they collect plant fibers and 鈥渃omb鈥 them into the lining of their nests.

"The Brown Belted Bumblebee (Bombus grisecolis) on my gardening glove was encountered during Master Naturalist work, at the Judge Morris Estate section of White Clay Creek State Park, where I met with a dedicated group of volunteers every week for environmental stewardship activities. I had accidentally dug this one up with my soil knife trying to get a stubborn knot of linden viburnum roots out of the ground for our forest restoration efforts, but she was understanding and just sat on my glove and brushed the dust off for a while before buzzing off."

"The shiny green one on an aster is Augochlora pura, a pure green-gold sweat bee, taken at my beloved Delaware Museum of Nature and Science, where I did a free year-long program on the connections between plants and insects. It was taken in late October 2023, when I was teaching about solitary bees and the importance to have a variety of nectar sources through the entire season."

"The last one in flight is Bombus perplexa, the confusing bumble bee. I just love how little and fuzzy they are and this one had his tongue out!"

"This one shows Bombus (Psithyrus) suckleyi, a species of cuckoo bee. They are so-called because like cuckoo birds, they kleptoparasitize the nest of a host species. In this case, these bees parasitize social bumblebee nests by killing the resident queens, usurping the throne, and having the resident colony raise their young. I spotted this bee on a hike in North Vancouver a few weeks ago, she was searching for host nests as you can see in this photo. You can tell Psithyrus from Bombus mostly by the sparsity or even absence of hair (also called 'pile') on the abdomen, and by the lack of pollen baskets (since they have been lost secondarily due to their lifestyle)."

"This photo shows a diverse assemblage of bees, which I found on a pile of scat while hiking in the Brazilian cerrado. The largest bee is Centris confusa, and is quite cool because it collects oil from plants! Other bees you can see include Trigona and Melipona species. A few years ago it was discovered that salt is an important component of nectar, and I speculate that they are lapping salts and perhaps other micronutrients from this scat. Given the location and morphology of the scat, mammologists have speculated that this scat belongs to a maned wolf (which I actually did see in the area that week!)."

"I was involved in working with honeybees before becoming a Master's student at 大象传媒. Here is a photo from some of my field work in Langley, you can see queen cells and larva along the edge of the frame as things were starting to get a bit crowded in the hive."

"I found a bee struggling to stay still on the bus. I reached out and held it gently until we got off. Unfortunately, there were no flowers around, but it circled me twice before flying away鈥攍ike a quiet thank you. The tiniest sweetheart馃崁" Sona Han
