"Buzzing Heroes: Unleashing the Power of Wild Bees as Earth's Unsung Pollinators"

Honeybees are social insects that live in colonies. They are managed by beekeepers and often used for commercial pollination. The remaining bees, often called “wild bees”, usually don’t have as complex social structures with many of them living a solitary life. In doing so, they don’t need to produce large amounts of honey.

Wild bees are important pollinators. They pollinate a wide variety of plants, including many that are important for food production. Honeybees also pollinate plants, but have been shown to be less effective at doing so. One possible factor being the dilution of pollen due to their generalist feeding behavior.

Wild bees, and other insects as well, are declining at a high rate for a number of reasons, including habitat loss, pesticide use, and also competition from honeybees.

One of the main reasons why wild bees are declining is habitat loss. In many parts of the world this goes hand in hand with replacing structured landscapes (=variety of habitats) with monocultures that don’t offer much.

But it can also be as simple as mowing your lawn too often and not allowing flowers to grow.

Many of those wild bees are highly specialized as well and are dependent on a certain flower species. If that flower goes, so does the bee.

Pesticide use is another major threat, not just to bees but insects in general. Pesticides can kill insects directly or indirectly. They can also weaken them, making them more susceptible to disease.

Honeybees can also pose a threat to wild bees as competition for food. Possible factors are larger size and higher number of individuals in a honeybee hive.
