Erosional Habitats for Bees
Eroding banks such as these are often seen as an eye-sores or safety hazards but they also create nesting habitats for a diversity of ground-nesting bees, wasps, and their associated parasitoids. While erosional features such as these are temporary habitats in the long-run, the habitats they do create can be hugely important for local bee populations and they often attract large aggregations of nesting bees.
Here's a few thoughts, observations, and just cool entomological things to share. Enjoy!
