This study was published in Science last week, and the authors asked me to illustrate the species represented in the study. Illustrating these species involved research into the behavior and social structures of each species. Some of the solitary bees pollinate only specific flowers while the social bees have fascinating behaviors associated with their queens or honey pots. I incorporated some of these particularities into each illustration. The paper can currently be found online and will be published in print later this year.
