Explore a collection of galleries of pollinators found in national parks

Many of the photographs were taken during pollinator inventories in national parks across the US. Although these inventories often focus on bees and butterflies, the collection also features beetles, moths, spiders, and birds that transfer pollen as they move from bloom to bloom.

Adding garden beds with blooming plants to an existing lawn can support bees

Blooming wildflowers, shrubs, and trees can provide the nectar and pollen these pollinators need but do not get from grass. Other tips include leaving patches of bare soil for ground-nesting bees to lay their eggs and filling birdbaths with large pebbles for them to land and drink from safely.

Coevolution of pollinators and flowering plants diversified both

The first pollinators were beetles, which consumed pollen before flowering plants existed. Over time, plants evolved to attract more insects and improve the uptake of pollen, while insects adapted their biology to enhance the capture of pollen, such as developing specialized mouthparts.

Bees are crucial for pollination and food security

When animals and insects pick up the pollen of flowers and spread it, they allow plants, including many food crops, to reproduce. The most common pollinator is the bee, but bees are at risk from pollution and pesticides.

Appropriate timing of land management techniques can help support pollinators

The mowing, grazing, and burning practices used to maintain land should be tailored to the life cycles and needs of native pollinators, particularly those of rare or endangered species. For example, mowing is recommended in the fall or winter when flowers are not in bloom.

Native, wild bees are at much greater risk of extinction than honey bees

It is estimated that there are more honey bees, which often compete with native bees for resources, on the planet than at any point in human history. Meanwhile, 40% of invertebrate pollinator species, including wild bees and butterflies, face extinction in the coming decades.

Bees are more likely to remember a flower if its nectar contains caffeine

Plants want pollinators to keep coming back, so the finding suggests that some plants, such as Citrus and Coffea species, have evolved to include caffeine in their nectar. Researchers suggest the findings could help develop methods to reinvigorate pollinator populations.

Over 1,500 insect species pollinate plants in the UK

These insects—including bumblebees, moths, butterflies, and beetles—play a crucial role in the reproduction of flowering plants, also known as angiosperms. They do so by transferring pollen from the male reproductive organ—the anther—to the female one—the stigma—which enables the plant to produce fruit.

Human beekeeping has been traced back to 7000 BCE

Eighty-seven of the world's leading crops rely on pollination in some way, including 43 that are highly dependent or entirely reliant on it. Without pollinators, key foods such as apples, avocados, and almonds would likely become extinct, pushing entire ecosystems into collapse.

Efficiency of commercial honeybees may exacerbate population declines in native bees

Commercial beekeepers are increasingly breeding honeybees on public lands, raising concerns among environmentalists that they’ll compete with and introduce new diseases to already threatened native pollinator populations. However, native species alone are often unable to meet the pollination levels required to meet necessary crop yields.

Contributing to one in every three bites of food consumed by humans, bees are a keystone species because of their essential role as pollinators of about 80% of all flowering plants worldwide.

Pollinators help develop seeds by transferring pollen between flowering plants

As bees approach a bright, colorful flower for nectar, they bump into its stamen—the flower's male reproductive organ—and pollen gets stuck to the pollinator's body. This pollen can then be deposited on another flower's sticky pistil—the flower's female reproductive organ—which brings the pollen down to the ovule for fertilization.

About one-third of the world's food supply depends on pollinators like bees, butterflies, and bats to transfer pollen between flowers, which use bright colors, scents, and nectar to attract them.

In Amsterdam, planting organic flowers has increased native bee diversity by 45%

The citywide effort is an example of rethinking conventional agricultural methods, which rely on monocropping and heavy chemical use. Cover crops—plants grown to suppress weeds, prevent erosion, and attract pollinators rather than to be harvested—have also shown environmental benefits, despite not being sold for profit.

Millions of honeybees are hauled yearly across the US to help pollinate farms

As indigenous pollinator populations dwindle, farmers increasingly rely on commercial honeybees, which truckers often transport during cooler periods to prevent die-off from overheating. Pollinating all the almond trees in California requires 85% to 90% of all honeybees available to pollinate in the country.

South Asia and sub-Saharan Africa are most at risk from falling pollinator numbers

Researchers at the Harvard T.H. Chan School of Public Health found that declines in pollinator populations would lead to higher rates of nutritional deficiencies, particularly in developing nations. Nations with large populations, such as China and India, would also be significantly impacted.

Solar panels can create pollinator-friendly habitats by protecting flowering plants

An example of agrivoltaics, where land is used for solar energy production and agriculture, the panels provide clean energy while also shading plants from excessive sunlight. Pollinator-friendly plants can improve water quality and reduce soil erosion by obstructing the wind.

Agricultural intensification has accelerated declines in pollinator populations

The practice of using farmland more frequently to increase its yield increases the number of residual pesticides and decreases botanical biodiversity. These processes tend to decrease carrying capacity for pollinators by eliminating food sources and nesting habitats.

Bees evolved from meat-eating wasps that became vegetarian

After flowering plants first appeared approximately 140 million years ago, some wasp diets would have changed as they consumed pollen-coated insects that would visit these plants. Bees that branched from these wasp species also developed long tongues to slurp nectar and ultraviolet vision to identify flower patterns unseen by humans.

Swarms of mechanical bees may one day support natural pollination

Engineers are racing to create tiny robot bees that can be programmed to mimic natural bee behavior, helping in specific scenarios such as indoor farming and space agriculture. Battery life challenges may be solved by having these robots accompanied by a nearby "mother" drone power supply.

Distinct plant species evolved to produce caffeine as a pesticide

Although it provides a defense against insects trying to eat caffeine-bearing plants, the molecule is an example of exaptation, where its original function was repurposed over time. Studies show that some plants now produce caffeine-laced nectar to help pollinators move more quickly and pollinate more efficiently.

Tracking butterfly migration via the pollen they collect

Trillions of insects migrate around the world each year, but many are too small to track with physical trackers, leaving their migratory routes a mystery. In recent years, scientists have utilized pollen grains collected from butterflies to analyze which plants that pollen originated from—providing substantial data to infer the insect's specific route. Research has shed light on many insects' migrations since, including the Painted Lady butterfly. Read more and see a map here.

Butterfly populations have declined by 22% from 2000 to 2020

Research suggests that one in every five butterflies is lost due to pesticide use, habitat loss, and climate change. Playing a vital role in pollination, their declining populations threaten plant reproduction and the health of ecosystems.

Benign species can become invasive if introduced into predator-free habitats

Most ecosystems contain organisms that, over many generations, have evolved into a stable balance with one another and their surroundings. In a new environment, a species may no longer be restricted by the limiting factors it is used to, and the native organisms in the area may not adapt quickly enough to the invader to establish a new balance.

While invasive species typically harm ecosystems by outcompeting native organisms for resources, some provide unexpected benefits, including new shelters, nesting habitats, and reduced environmental heat stress.

Microbial research suggests shifts in diverse populations may help an invasive species establish itself

In 1958, English ecologist Charles Elton suggested that diverse ecosystems should be more resistant to invasive species because gaining a foothold would be more challenging when resources are more thinly spread. However, in lab-grown microbial ecosystems with greater biodiversity, population volatility opened more ecological roles that invasive species could easily fill.

Santa Barbara’s Botanic Garden was the first to showcase the state’s native plants

Founded in 1926, the garden’s founders sought to showcase the state’s local flora as a matter of conservation, rather than the water-hungry exotics regularly being imported. This story focuses on how the garden’s design took a more natural and less formal direction.

Some police departments in California have officers specialized in hive crime

The cost of a beehive climbed from about $35 in the early 2010s to $200 as of 2020, which has incentivized some to steal hives at night. These kidnappings led to the creation of dedicated task forces in the state, whose almond farms have created an extraordinary demand for pollinators.

Biosphere 2 revealed limitations in maintaining wildlife in unfamiliar environments

Trees appeared to become weak and more prone to breaking because a lack of wind caused them to no longer need to develop stress wood. The extinction of pollinators—potentially due to an explosion in the population of longhorn crazy ants—was also unexpected.

Some mosquitoes are key pollinators—and eat disease-carrying mosquitoes.

Chaos gardening involves scattering seeds without any planning

The trend is intended to produce colorful, dense gardens by mixing various seeds. While encouraging experimentation and lower stakes, the success of these gardens depends on choosing plants with similar needs and incorporating native, nectar-rich flowers.

Some invasive plants, such as English ivy, maiden grass, and Norway maple, can swiftly take over gardens and damage yard structures if left unchecked.
