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.
Bumble bee colonies are often located underground in deserted rodent nests or other cavities, in compost piles, and underneath objects on the ground. Some species will nest higher up in trees or wall cavities as well as in bird houses and bird nests (figure 21). Like honey bees, bumble bees construct cells made of wax.
