Our Photo Survey Protocol

Keeping social distancing a priority, we are switching this year's BeeBlitz to a remote affair. On June 27th, please join us in a photo survey of your yard, local park, or wildland.

A standardized survey aims to photograph bees for the same length of time, at the same time of day, in the same place, on the same flowers, and under the same weather conditions over the course of a number of successive months and years. That way, the samples can be compared as a series of like items.

We have created a simple protocol for conducting a standardized photo survey. We are currently focused on bumble bees, because they can be identified using photographs in this region and they are important native pollinators of wild and cultivated plants. All observations can be submitted to iNaturalist using the unique tagging system for our project: STL BeeBlitz.

Checkout our handy "cheatsheets" with reminders, important details, and recommendations:

Photo-Survey Protocol Details

In order for this photo survey technique to work most efficiently, it is helpful to have your photographs geo-referenced. If you are using the camera on a smart device, turn on the GPS:

    • iPhone: Settings => Privacy => Location Services => Camera => While Using the App
    • Android: Swipe down dashboard: Settings (in top right) => Security => Location => On
    • Google: Swipe down dashboard: Settings (in bottom right) => Security and Location => Location => On

If you are using a traditional camera, please follow the instructions for geo-referencing your photographs (details are provided in the section below)


  1. Observations should be made on mostly sunny, warm days between 10am and 2pm. Bee activity changes with the weather. If it is overcast and cool, fewer bees will be foraging. To minimize the effect of weather on our counts, we only collect when the weather is optimal for these insects.
  2. Observe the location area. What kinds of plants are flowering? Which are most abundant? Which are the bees favoring?
  3. Place your first 2m x 2m plot on a patch of flowers at your observation location that is representative of flowering diversity. Record the plant species name(s), if known.
  4. Label your whiteboard with: the location name and plot name, so you can keep track of which photographs were taking in which plot.
  5. Take a photograph of the whiteboard with the Location name and 2m x 2m plot number (e.g., “PCA plot1”). Check our tips for Photographing Bees for identification purposes. It also helps to practice, practice, practice (particularly before your first official survey).
  6. Observe that plot for 10 minutes, taking several photographs of every bee that you see from multiple angles.
    • To help you keep track of each bee observed, take a photo of your hand or whiteboard in between each individual bee’s photos.
  7. Choose up to 10, 2x2m plots that represent the flowering diversity (both the number and relative abundance of each species) in that location. Plots must be a minimum of 5 m apart. REPEAT steps 2-7.
  8. At the end of your survey, submit your observations to iNaturalist
