Hello everyone,

Firstly, thanks to every observer who has contributed to the Bee-Flower Interaction Project over the past year. We know adding plant identifications is not always easy, and we are only thankful to you for the time and effort that you have put in. We also thank people who are more familiar with plants for their help in identifying plants.

We have been wanting to follow-up with an update and to be able to present the data that we’ve gathered so far. We hope this journal update serves that purpose.

To begin with, here’s a distribution of all the observations that have been added to the project. As evident, we need to add observations from more regions of the country to make sure that the data is reflective of the diversity, and also continue adding more observations. Any help towards achieving this is welcome, and we look for your continued support.

The project has seen over 1700 observations from more than 250 individual observers, and covering more than 86 unique groups of Bees. These observations have revealed interactions of bees with more than 175 unique groups of plants. Here is a quick look at the most commonly observed bees under the project so far, with Xylocopa and Apis cerana leading the count:

Next we have the most common plant groups that the bees documented under the project have interacted with. Calotropis flowers (one of the Milkweeds) are the most commonly interacted with.

Next we have the total number of unique plants that each set of Bees have interacted with. For instance, Apis cerana have been seen interacting with a total 95 unique plant groups, Xylocopa bees with a total of 75 unique plants, and so on.

As you can imagine, the overall dataset is quite complex to be able to present in the form of charts or other visually pleasing means. So, we’ve compiled a table with all the plants that each of the bees have been documented around. Note that we’ve excluded a few observations that had plant IDs only at ‘Plantae’ level as those observations need more refined IDs. Also note that there will be some overlaps here as plant IDs sometimes are only at a family level, while others may have the exact genus or species within that family. For example, we have Asteraceae under Apis cerana while Cosmos or Tridax are also present in the list. In the long term, we may need to try and refine as many plant IDs as we can, so that the data is less overlapping while accounting for as much of the data as possible.

Again, we would like to thank every individual who has contributed to the project in the form of observations, plant IDs and in every other way.
