Do native bees occur on every continent on the planet?

Native bees occur on every continent except Antarctica. Wherever there are insect-pollinated flowering plants—be it in forest, farms, cities, and wildlands—there are bees. And just because you don’t see obvious blooming plants, that does not mean that there are no bees around. Look down! Those tiny flowers that you see on some plants are also supporting billions of equally tiny bees.

Does the loss of plant diversity affect the health of native bees?

Loss of plant diversity is the primary cause of native bee decline. About 30-50% of all native bees are highly specialized, so if the plant they rely on disappears, the bees go away. If the bees disappear, the plant is unable to reproduce and dies out. While some of the plants pollinated by native bees are important food crops, other plants...

Do bees feed on both nectar and pollen?

Bees feed on and require both nectar and pollen. The nectar is for energy and the pollen provides protein and other nutrients. Most pollen is used by bees as larvae food, but bees also transfer it from plant-to-plant, providing the pollination services needed by plants and nature as a whole.

How many species of native bees are in the United States?

There are over 20,000 known bee species in the world, and 4,000 of them are native to the United States. They range from the tiny (2 mm) and solitary Perdita minima , known as the world’s smallest bee, to kumquat-sized species of carpenter bees . Our bees come in as many sizes, shapes, and colors as the flowers they pollinate. There is still much...

Are honey bees native to North America?

Honey bees are not native to North America. They were originally imported from Europe in the 17th century. Honey bees now help pollinate many U.S. crops like fruits and nuts. In a single year, one honey bee colony can gather about 40 pounds of pollen and 265 pounds of nectar. Honey bees increase our nation's crop values each year by more than 15...

What is the role of native bees in the United States?

About 75% of North American plant species require an insect—mostly bees—to move their pollen from one plant to another to effect pollination. Unlike the well-known behavior of the non-native honeybees, there is much that we don’t know about native bees. Many native bees are smaller in size than a grain of rice. Of approximately 4,000 native bee...

Why are pollinating bats, birds, bees, butterflies, and other animals important?

Do you enjoy a hot cup of coffee, a juicy peach, an-apple-a-day, almonds, rich and creamy dates, a handful of plump cashews, or vine-ripened tomatoes? Do you enjoy seeing the native flowers and plants that surround you? If so, you depend on pollinators. Wherever flowering plants flourish, pollinating bees, birds, butterflies, bats and other...

Why are bats important?

By eating insects, bats save U.S. agriculture billions of dollars per year in pest control. Some studies have estimated that service to be worth over $3.7 billion per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems and the degree to which that...

USGS Scientists are Busy as a Bee

Many bumble bee species have declined in recent decades due to changes in habitat, climate, and pressures from pathogens, pesticides and introduced species. The western bumble bee, once common throughout western North America, is a species of concern and is being considered for listing by the U.S. Fish and Wildlife Service under the Endangered Species Act.

Pesticides, Pollinators, and Pestilence: Protecting Public Health and Pollinators

Tick and mosquito control provides important public health protection, but can also affect pollinator populations. The effects are often dependent on specific local conditions, such as how close the pesticide application is to places pollinators frequent, and when they frequent them.
