North American Bumblebees
And Bumblebees Of
Central America And Mexico

The USA has over 3,000 known species of bee, and of these, about 40 are bumblebees (i.e. of the genus Bombus).

As in other areas of the world, bumblebees are a cause for concern

Bombus franklini and Bombus occidentalis are unfortunately believed to be on the brink of extinction/facing very serious decline.

Wherever possible, please try to do your bit to help if you can.  In particular, please try to leave bee nests alone.  I do not recommend killing bumblebees even just to 'take a closer look' or 'to collect' them.

Threats to bumblebees include:

  • habitat loss: due to intensive agriculture, urbanization and building development;
  • the use of pesticides,such as neonicotinoids;
  • general pollution, and
  • the introduction of diseases and parasites from Europe due to commercial trade in bumblebees for pollination (i.e. for using in pollinating greenhouse crops such as tomatoes) - read more on my page about commercially reared bumblebees.

Here is a list of North American bumblebees, including cuckoo species.

(Note ‘B.’ stands for Bombus).

Bumble Bees of North America

Read my review

The book, 'Bumble Bees of North America' is a a good identification guide. See my review and description here.

Another book I heartily recommend is 'The Bees In Your Backyard'....

What do bees eat?

Bees eat pollen and nectar

- everyone knows that!

But what else do they eat?


Do bees sleep?
Apparently they do, but how do we know?
