a separate study from the one posted below shows that bees can't taste pesticides even when they're at lethal levels:
A new study has confirmed that pesticides, commonly used in farmland, significantly harm #bumblebees. Data from 106 sites across 8 European countries show that despite tightened pesticide regulations, more needs to be done

If you don't know about neonic-treated crop seeds, I recommend this book, Restoring Eden by my friend Elizabeth Hilborn, whose farm and its wildlife, ￼from insects to tadpoles, were poisoned by accidental contamination from a neighbor's pesticide-treated corn seed.
EPA is seeking comments on whether to regulate neonic-treated seeds as pesticides. Please comment! This is an extremely important i￼ssue. Most crop seeds, especially corn, are treated with these pesticides, harmful to wildlife and humans.
You won! 👍 I just invited my interview guests: a Cactus from the Ecuadorian Andes and Geoffrey's tailless bat. It's still not sure if a certain pitcher plant from Borneo will join us. The technical setup will be incredibly complex, but no effort is too much for me. You will be able to follow the conversation thanks to my micro macro amplifier. I have certain tricks to make the conversation between Cactus and Bat audible. Secret: We'll have bat tequila.🤫 #NatureMatchCuts #podcast #pollinators
Pollinators are an important part of the ecosystem, they move pollen within them or carry it from one flower to another. 🌱🌸

"#Insect-pollinated plants react more strongly to a warming climate than self-pollinating plants, and flowers with earlier bloom times are more sensitive than species that bloom later in the season.
In some cases, co-dependent species both emerge earlier and continue the relationship needed for their mutual survival — a process scientists refer to as a “linear advancement.” While some studies suggest that #pollinators might be robust enough to withstand climate disruptions, a growing body of research illustrates just the opposite. Scientists cite global warming as “one of the biggest anthropogenic disturbance factors imposed on #ecosystems." #climate https://therevelator.org/climate-change-protecting-pollinators/
Since Stormbird and others (Maestro Tree Frog and progeny) have been calling out for rain in the evenings, we took the opportunity to plant out some buddleia plants (butterfly bush), two different types of ginger (native and edible), and some palm trees - to help fill in a pocket of rainforest canopy and provide food for insects and birds.
During late winter, masses of bees and native parrots feed on local palm blossoms (and later fruit) when little else is in flower. And in the long term, cool shade will be at a premium for all living things during the hot summers ahead.
New study reveals that bees cannot taste even lethal levels of pesticides
New research from the University of #Oxford has revealed that #bumblebees cannot taste #pesticides present in nectar, even at lethal concentrations. This means bumblebees are not able to avoid contaminated nectar, putting them at high risk of pesticide expos

Today I'm checking the second proofs of my new book "Birds & Flowers: An Intimate 50 Million Year Relationship" and I thought I'd share this short piece from Chapter 3.
A very interesting morning at the event to mark the ending of the EIP protecting farmland pollinators project. For a small project, only 40 farms, we had a good turn out with 2 junior ministers from DAFM and several dept officials present ( one minister was a participant in the project on his own home farm). It was a good project, while the knowledge gained will undoubtedly be used on the official side its a pity there is no pathway to continue the farm side. #bee #entomology #pollinators
There’s so much good science and so many great talks coming out of the (broad) field of pollinator and pollination research at the moment! Here’s a few things that have come up on my radar. Feel free to comment and add your own examples of things I may have missed: https://jeffollerton.co.uk/2023/11/13/recent-research-and-seminars-on-pollinators-and-pollination-that-have-caught-my-eye/
Bees on Milkweed
These cold and bleak fall days our wild and honey bees are nowhere to be seen, so it’s lovely to look back on the halcyon summer days when this scene was so common. Who would have thought milkweed flowers were so lovely? Have a lovely day, friends. This was taken with my 180mm macro lens. Have a good day, friends.

Crops that provide most of our vitamins and minerals, such as #fruits, vegetables & nuts, depend on #pollinators and organisms in the #soil that keep it fertile. An estimated 75% of #food crops rely on pollinators to some degree."
Planting for #pollinators under solar panels is a great idea. Just remember to keep maintenance in the plan. #bees
"#Trees are an important, stable source of food for #bees and other #pollinators providing thousands of flower heads all in one place. Love trees and bees? Here you'll find five lists of trees for bees 1. Trees for Bees that also provide fruit or nuts 2. Nitrogen Fixing Trees for Bees 3. Ornamental Trees for Bees 4. Master list including all of the above in alphabetical order (including USDA hardiness for each species) 5.

Who goes to the zoo and takes pictures of flowers? 🙋♂️ Only after getting home and sorting the pictures did I notice the pollinators buzzily working these blooms were mostly wasps, not bees. Searching online revealed wasps are as critical pollinators as bees are. TIL.
🌸 🐝 Our newest team member is Henning Nottebrock, a plant ecologist fascinated by pollination @unifreiburg #NatureScientistsUFR. His research focuses on demographic processes of #plant communities mediated by #pollinators in natural & agricultural ecosystems🌽 🌳 🚜
Very few insects left this time of year around these parts but I've seen several clouded sulphurs like this one I came across across last Thursday (one of two that day).
"...a product of my life's work, from day one in 1977 until today."
The rich history and semantics of _Afrotropical Bees_ from Connal Eardley, Willem Coetzer, Joseph Monks and collaborators is now in @TaxonWorks, may it see another half decade of curation! More news as the project settles in.
Do you have a life's work in a taxonomy-based knowledge-base, and collaborators looking to extend it? The Species File Group (https://speciesfilegroup.org) is interested.
A bit late for #FlyDay. Anyway, please enjoy this lovely syrphid fly, a striking dark brown/black with bright yellow stripes nectaring on a bright purple/blue aster with a yellow center.
Salvia greggii is my best #pollinators (insects and hummingbirds) plant.
1. Everblooming. 2. The F'ing Deer hate it.
Today, having in mind the American Ornithological Union's new decision to change the common names of birds named for people, I looked up Josiah Gregg the botanist. Hoping he wasn't the a-hole.
Did that guy live an interesting life. Explorer, botanist, physician (whole 2 semesters med school), war correspondent & interpreter, mapmaker, and '49er. Interesting death, too.
His anger at being left behind by his explorer pals near Trinidad, Calif., reportedly gave the Mad River its name.

I hung out at the 'Hot Lips' salvia for a while today, hoping to catch an interesting native species or event among the pollinators. With 1,600 species of native bees (that's just bees, not even including flies or wasps) found in California... ya think? But the bush was swarming with only (sorry, Ben) European honey bees. I did catch this nice moment when one sunlit bee was brushing against the anthers while nectaring.

For you maybe…but I’m still on summer time!
How bright are your evenings now?

It's a beautiful October day, and I feel reflective. I miss the summer hustle-bustle of insects, frogs, birds, and reptiles. Many are still present, but I know they are finding a place to hibernate or be out of the cold. Some have died or will die soon. But they have fulfilled they purpose. The spark of life that created me is the same spark of life that they carried. We have met, and now we part. Thank you for being part of my world. #wildlife #pollinators #Insects #gardening
Our West Country Buzz project has been busy sowing seed to create a new meadow 🌸🐝
Yesterday the project sowed #wildflower seed at Tapeley Park to create a flowery meadow to benefit #pollinators and other wildlife! Creating bare ground is important as is rolling after sowing to ensure the seed can germinate well 🚜🌻
Coffee and Cocoa Plants Especially at Risk From Pollinator Losses #coffee #cocoa #environment #pollinators https://www.ecowatch.com/pollinator-losses-crop-impacts-cocoa-coffee.html
Still busy collecting, not too cold yet.
We are in October but the hard cold hasn't hit yet and on sunny days like this one was, the bees are frantically busy, lining up for a feed, like Grand Central Station at the ticket counter.
Have a great Friday, Fedi Friends.
A new study has found that it's key tropical crops like #coffee, #cocoa and #mango, that support millions of farmers in the Global South, that are most at risk from loss of #pollinators due to #climatechange and land use – read about it here:
It's late in the season in my garden, but there is still something to celebrate - something new worked!
It all started when someone from Mastodon recommended to me to put out some Anise Hyssop for late season #pollinators. I ordered a few and put them out. Later, I found a #Beautyberry shrub growing in the wrong place. I moved it next to the Hyssop thinking the colors might be complementary. Got a pic just in time.
Who recommended the Hyssop? I forgot!
Open to see both together.
Another sunny #bee day is coming. Did you know that the interieur of a #sunflower shows a beautiful #violet circle for #bees and other #pollinators? Human sight sense is too restricted to see it. Our eyes only needed the ability to see the ultraviolet spectrum: https://en.m.wikipedia.org/wiki/UV_coloration_in_flowers
