OVERVIEW OF LESSON / BACKGROUND Most people can describe or draw a basic bee: black and yellow stripes, wings, a 3-part body. This lesson will take students beyond the basics by bringing the honey bee’s amazing anatomy and structures alive. From the pollen basket to the hairy eyes, bees are creatures that inspire wonder and curiosity. Although each of the 20,000 species of bees in the world has something in common with the next, this lesson focuses on honey bees: the only insects that produce food for humans. In order to survive, thrive, and perform their work in the world, honey bees have evolved with a fascinating anatomy and specific adaptations. This detailed, up-close look at both the structures and the functions of honey bee anatomy will help students understand the bee’s place in the world. Honey bees have many parts that are easily recognizable: a head, thorax, abdomen, legs, antennae, eyes, wings, etc. They also have a corbiculae (or pollen basket), tiny hairs on their eyes, a proboscis, and hooks (or hamuli) that hold their wings together in flight.

Similar to honey bees (Apis mellifera), stingless bees (Meliponini) belong to the category of proper social insects and are at the highest level of social development. This group of insects comprises about 500 species and they are the most common bees pollinating the native plants in many tropical areas. Families of stingless bees are usually quite numerous, reaching up to 100,000 individuals. They are characterised by polymorphism, age polyethism and perennialism. This article presents the structural complexity of natural nesting of these tropical insects and their ability to settle in artificial nest traps. The main significance of stingless bees for humans is their role in the natural environment as pollinators, which is an essential factor influencing biodiversity. © IOŚ-PIB 1. INTRODUCTION Ctenoplectridae). Similarly, as in Europe, representatives Bees (Apiformes) represent a very important element of 6 families occur in Poland: Colletidae, Andrenidae, influencing biodiversity; as active pollinators. They play Halictidae, Melittidae, Megachilidae and Apidae; the latter a key role in maintaining the species richness of many includes the Anthophoridae.

  • External Observation of Honey Bee
    External Observation of Honey Bee Name ___________________________________ Date ____________________________ Background Information: Honey bees have many interesting structural adaptations to help them survive and function as pollinators. Today you will get an up-close look at those structures, using binocular / dissecting microscopes. During your observations, refer to the drawing for identification of the different parts. You will be using 3-4 honey bees for your observations. Refer to several specimens since some bees will be missing parts due to collection and shipping. You will need to compare bees in order to make accurate observations. Materials: Dried honey bees (3-4 per student group) Binocular / dissecting scope Forceps and probe Ruler Petri dish Directions for external observation: 1. Using your forceps to hold the bee, look at the bee under the binocular microscope. Look for different parts as you turn your bees around and make an initial survey of your specimens. Bees are covered with little hairs that pick up pollen. Pollen that is not in the pollen baskets can be dropped off at other flowers for fertilization. 2. Look for the two sets of wings on your bee (forewings and hindwings). Wings are important for flight so the bee can fly from the hive to the flowers (their food source). Bees are unique in that their two sets of wings “hook” together during flight to make one larger wing. Sometimes, bees “fan” the hive to help cool it off. Use your ruler to measure the length of several forewings and record those lengths for your bees. Draw a picture of a forewing as it looks under the microscope (include the veins and hairs on the wing).

  • What Makes a Good Pollinator? Why Is Pollen Sticky?
    What makes a good pollinator? Dependence on flowers for food o Bees aren’t trying to be good pollinators. They are visiting flowers to gather food and in the process come into contact with pollen grains. Their attraction to flowers is part of what makes them a good pollinator. Hairy bodies and pollen carrying structures o Bees generally have hairy bodies that trap pollen grains. As they move from flower to flower, some of it brushes off. Some bees even have a special structure called a corbicula (a pollen basket), which is used to collect and carry large quantities to their home. Floral fidelity (Visiting flowers from the same plant species) o When bees find a valuable food resource, they tend to forage on that species exclusively until it is gone. This means more pollen is being transported to the same plant species for cross-pollination. Why is pollen sticky? Wind-pollinated plants produce lots of lightweight, smooth pollen. However, insect-pollinated plants don’t produce as much pollen and the pollen is heavy and sticky. When an insect visits a flower for food, the pollen gets caught in hairs for easy transport to another flower. What insect body parts or structures make Dandelion pollen pollination possible? Pollinators use their eyes and antennae (sense of smell) to locate flowers (usually ones with bright colors that smell). Wings or legs allow pollinators to move easily from flower to flower, taking pollen along with them. Many bees are also great pollinators because they have hairy bodies. Pollen gets caught in these hairs and drops off on other flowers they visit.

  • Wasp, Bee, Or Fly?
    1 WHICH IS IT - WASP, BEE, OR FLY? The Order Hymenoptera includes many tiny wasp parasites, sawflies, ants, wasps and bees. Hymenoptera means “membrane wing.” Hymenoptera have two pairs of wings. Bees - Apoidea Females collect pollen and nectar . Nectar provides energy for the adults and grub-like larvae. Pollen is the nitrogen source for larvae. Most species have hairs on their body. In particular, females have hairs on the hind legs or underside of the abdomen , for collecting pollen for their larval offspring. Bodies tend to be rounder than wasps, and they tend not to have a conspicuous “wasp waist”. Antennae are thin and have many cylindrical segments. Female antennae are usually elbowed, whereas male antennae are longer than female antennae, and not elbowed. Males often have yellow or white hairs on the front of their face. Females create a nest of some sort to protect their larvae. They usually provision individual cells for each offspring, and then lay an egg on the provisions. Females have a stinger , which is a modified ovipositor, for laying eggs. The stinger is usually retracted into the abdomen. Males don’t lay eggs, so they don’t have ovipositors, so they don’t sting! Social species are the most aggressive about using their stinger, since workers do not lay eggs, and are expendable. HONEY BEE (Apis mellifera ): The most familiar bee species. Social, living in colonies with one reproductive queen, many female workers, and some males present only for a limited period of time. Colonies last for many years. Usually they are found in white wooden hives managed by beekeepers for honey production and agricultural pollination.
