John,

Strategic planning, creative imaginations and deep emotional lives. If you think I'm talking about people, think again.

As it turns out, bees are in the upper echelon of intelligence -- right up there with people and a few other vertebrates. They may be small, but their cognitive depth is massive.1

Here are a few things bees can do that might just impress you:

People might not be the only living creatures that feel sophisticated emotions such as joy, fear and optimism. Bees might, too.

Researchers found that bees' brains released dopamine and serotonin when they were given sugar. Bees may even experience fear and stress after traumatic events, and feel more optimistic about foraging after they've found a good food source.2

And these aren't just basic 'happy' and 'sad' emotions. Inside their tiny bodies, bees can experience complex emotions.

Bees just might just be speaking to each other in a secret code we don't understand.

Some bees 'talk' with each other through movements called waggle dances. They use these moves to express needs, divide up work to be more productive, share information and help each other find food sources.

When researchers studied these dances, they found that colonies have distinct "dialects," with different moves. In each colony, young bees watched more experienced bees' movements and learned how to dance.3

Whether by daydreaming or reminiscing about the past, most of us have active imaginations. It turns out bees use their imaginations, too.

Researchers have found that bees can conjure up mental images of objects they've seen before. A bee can pollinate a flower, for example, and think of the plant later that day. And, researchers think bees can even have vivid dreams while they sleep.4,5

Bees' tiny brains certainly don't work in the same ways ours do, but we can't overlook them just because they're small. Bees are far more advanced than we give them credit for.

We're awestruck by how clever bees can be. But these amazing bees need our help.

Right now, about 1 in 4 bumblebees are at risk of extinction because of threats like dangerous pesticide use and habitat loss. That's why we're working to restrict the worst uses of neonic pesticides and get them off store shelves.6

And, with your help, we're protecting pollinator habitat, so bees have safe spaces to call home.

Thank you,

Ellen Montgomery
