Yes, dreaming about how you want to get back together with an ex sometimes does mean that you're still carrying a torch for them. But it can also just mean that you miss being in a relationship and feeling wanted.
Some species including honey bees, bumble bees, and stingless bees live socially in colonies. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae.
Besides C. Inaequalis, many other ground nesting native bees can be found in your backyard. For example, species of the bee genera Agapostemon, Andrena, Halictus and Lasioglossum are also very abundant in North America (photo 4 - 6).
