You can help declining insect populations by planting groups of the same kinds of flowers together, researchers say. They act like big ads for bug food.

Until now, no one had properly tested Darwin's hypothesis on the link between cleistogamy and bilateral symmetry in flowers.

Predatory insects are super pest controllers. Planting flowers can help them help farmers to reduce the use of pesticides.

Bumble bees in low-quality landscapes with fewer flowers and places for nesting have more diseases and parasites, researchers say.

Archaeologists have long debated the relationship of psychedelics to rock art. New evidence from Pinwheel Cave in California clarifies the connection.

Milkweed is key to monarch butterflies' life cycle. But adding other flowering plants may help monarchs more than milkweed alone.

Sequencing the gardenia genome shows how plants evolved to re-use tricks from their genetic toolbox to create new chemicals.

When pollen resources are low, bumblebees damage plants to help drive more flowering so they can get more, researchers have found.

A wild dandelion's spiny pollen has evolved to attach to traveling bumblebees, report researchers.

Although there are pros and cons to flowering strips for bumble bees, they're a good way to offset pollinator declines, say researchers.
