![]() Without pollination, they cannot produce seeds they would not reproduce. Most of these are pollinated by various types of bees. Amid Missouri's array of woodlands, grasslands, and wetlands is a wide variety of wildflowers and other flowering plants. Native bees play a critical role in the health and integrity of our natural habitats. Cleptoparasites thus depend on their hosts for life. Some types of sweat bees sneak into the nests of other species, eat the egg of the rightful owner, and lay their own egg on the food provided. Honeybees are not capable of buzz pollination, so these plants are dependent on native bees to perform this important duty.Īn intriguing behavior that evolved in many insects, including several species of sweat bees, is cleptoparasitism ("clepto-" means stealing). Many flowering plants require buzz pollination to release pollen for reproduction. In this process, the bee grabs the anther of the flower in its mandibles, curls its abdomen around the anther, and vibrates its wing muscles, causing the anther to release its pollen. ![]() Halictids are some of the smallest bees that can buzz-pollinate. The family name is derived from the genus name Halictus, which means "to gather" or "to assemble." Apparently this is in reference to the mother sweat bee's gathering of nectar and pollen to feed her young. Halictid bees pollinate wildflowers, fruits and vegetables, and a variety of other crops. Halictids and other native bees are often specialists that evolved alongside specific types of plants and are the only insects capable of pollinating them. crops rely on native bees for pollination, so it's important to know that we need many more pollinators than just honeybees. Consider putting up a bee house.Ībout 30 percent of U.S. ![]() Reduce mowing to allow broadleaf plants in your lawn to flower. Avoid pesticides and any plants or seed treated with neonicotinoids, which are harmful to all insects, including bees (some neonicotinoid names to watch for on plant or seed labels are imidacloprid and acetamiprid). Plant flowers that will bloom throughout the season, especially early and late in the season, when fewer pollen and nectar sources are available. Fortunately, homeowners can easily help bee populations in their yards. The plight of wild bees should concern us all. It's kind of amusing to think that we are sports beverages for insects.Ī gentle scrape will usually persuade a visiting sweat bee to move on, but pressing on a female sweat bee may prompt her to respond with a mild sting. Sweat bees are famous - or infamous - for their tendency to land on humans to obtain moisture and salts from perspiration. Several other types of bees and wasps are metallic-bodied, too. Female cuckoo wasps cannot sting, which might explain the protective defensive posture in that group. Also, they can roll up into a ball for defense. Similar species: Cuckoo wasps (in family Chrysididae) are also small bee- or wasp-type insects in metallic blues and greens, but their bodies are usually covered with small pits, giving them a sculptured or pebbly look. ![]() One of the most noticeable traits of sweat bees is their attraction to perspiration, which offers them precious moisture and salts. Specialists note details of wing venation, antennae structure, and other characteristics to distinguish this group from other bees, and to distinguish the various sweat bees from each other. All have short tongues, compared to other types of bees. Their markings vary from green to red to yellow, often with bands similar to those of honeybees. Most members of this family are black or brown, but some are brightly colored, notably with metallic greens and blues. There are many species of sweat bees, or halictids, in several genera in Missouri. ![]()
