As promised, here are more x-ray pictures. This is another set of wooden blocks.
Do you see the super bright stuff near the bottom (which is actually the entrance) of the middle block? Those would be rocks. Lots of tiny tiny rocks that the female bees use to separate each cell and close off the entrance to the nest. The other bees use rocks, soil, plants parts like leaves, etc. The rocks show up brightly because they contain some calcium. Cool huh.
Here is a close-up of the bees inside the block on the left. These bees are already developing their body shape. They no longer look like beans or grubs. You can see the 3 major morphological features of these pupae. I have pointed them out using my awesome PowerPoint skills. Goodbear, don’t laugh.
Isn’t that cool to see. When I was looking through the x-rays and saw this I was so excited. I was just as exited as a mother looking at her babies first sonogram. To be able to see their development is just exciting.
