If you’re interested in feeding native bees, there are a few things to consider before you make a decision. First, you’ll want to consider how many bees you’ll be feeding, and whether you want to use a natural product or a man-made solution. Second, you’ll want to know how to best preserve their habitat.

Ground nesting bees
Ground nesting bees are solitary bees that have no queen and no sting. They dig nests in the soil, often in sandy areas of the ground. Some species build nests in dead tree stumps and hollow plant stems.
Ground-nesting bees are mainly found in North America. Most of the ground-nesting bee species in the United States and Canada are native. While they are less studied than cavity-nesters, there are several methods to study their behaviors and preferences. These studies may help land managers develop and maintain preferred habitat for the targeted bee species.
One method of studying ground-nesting bees is to sample entire communities. This is useful for determining the characteristics of a particular species and the performance of the bee under different conditions.
Another technique to study ground-nesting bees is to observe their brood cells. The female bees of Lasioglossum versatum, for instance, reseal brood cells immediately after laying eggs. Their bodies are covered in glandular secretions which create a waxy coating around the brood cells.
Stingless bees
Stingless bees are an important pollinator of native plants and crops. These bees are members of the Apidae family and live in colonies with tens to hundreds of thousands of workers. Although they are mostly found in tropical countries, stingless bees also occur in temperate regions.
These bees have a strong need for tree resin to form propolis. They also feed on nectar collected by foraging workers. As a result, their populations are threatened by habitat loss, competition for resources and pesticides.
Stingless bees are a member of the Meliponini tribe. These bees are mainly found in tropical and subtropical regions, with most species occurring in the western hemisphere. Some species are endemic to the Caribbean and other islands. The genus Melipona is the major pollinating insect for several species of plants in many ecosystems. In the Western Hemisphere, about 80% of the species are native.
Stingless bees can be found in different habitats, such as rocks and crevices, and hives. Their colonies typically include a single queen. Each nest contains a brood comb and a multilayered wax and resin called involucrum.
Specialist bees
The majority of bees are solitary, but there are also some bees that are semi-social. This means that they build nests in their own territory, but they also share a common entrance to the nest and are responsible for feeding the young.
These bees can be categorized into generalists and specialist bees. Generalists collect pollen from a wide variety of plant families, and they are out all season. In contrast, specialists collect pollen from only one plant family. They tend to have more specialized needs, and they do not do well when they have to live on the same diet as generalists.
Specialist bees are usually only out during the blooming season, and they are only out for about five weeks. During this time, they feed the young with pollen from only two or three different plant species.
The specialist bees are the most important of the bees. In fact, the population of the specialist bees accounts for about 20% of the total bee population.
Preserving habitat
Preserving habitat for native bees is a critical goal to protect the pollination services that our society depends on. As wild bees decline, we are losing biodiversity, food security, and many other important ecosystem services.
Habitat loss is the primary driver of bee decline. In the past century, agricultural expansion has pushed wild bees from their native ranges.
Restoration has been shown to have positive effects on wild bee abundance. Typical restoration actions include seeding native flora, reintroducing grazers, and reinstating historic fire regimes. However, the success of these programs depends on the ability of bees to reestablish healthy populations.
Several factors have been implicated in bee decline. Some of these include loss of nesting sites, alterations of soil texture and moisture, and increased temperature. Those changes have a direct impact on bee development, emergence, and abundance.
Other factors that have been linked to declines are agrochemicals, pesticides, and parasites. In addition, disease can cause harm to solitary bees.
