There is a narrow constriction between thorax and abdomen (it is a thread-waisted wasp). It is a type of digger wasp, and most people see it busily eating nectar and pollen from flowers in summertime. Wasps never have pollen-carrying hairs (although masarid wasps feed on pollen). The great black wasp is a strikingly large, black wasp with smoky black wings that shine with blue iridescence. Think of a “wasp waist” a constriction in the petiole than many wasps have. Bees are also usually hairier and more robust than wasps. When magnified, bee hairs are branched (plumose) not simple and straight like those on wasps. One hair character sets bees apart from wasps. Wasp Identification: Wasps have four wings, chewing mouthparts, a sting in females, and long antennae. Many flies have huge eyes that meet at the top of their heads. Because honey bee nests can grow quite large in size, this puts homes and businesses at risk of structural damage. They have piercing/sucking or sponging mouthparts. Flies usually have short, stubby antennae with single hairs, or feathery antennae. So, how do you tell these pollinators apart?įly Identification: Flies have only one pair of wings, while bees have four wings. By mimicking bees and wasps in appearance, they gain protection from predators. the Syrphidae) are bee and wasp mimics in color, form and actions. There are two kinds of insects that are often confused with bees - flies and wasps. The abdomen contains digestive organs and the sting in females. The thorax bears the legs and four wings (two forewings and two hind-wings coupled by tiny hooks). The head has the compound and simple eyes, segmented paired antennae, and mouthparts including mandibles for biting, and the proboscis for drinking nectar. This guide gives information for identifying 10 major groups of bees commonly observed in Arizona including key characters, sizes (in mm), nesting habits, floral preferences, and distinctive behaviors.īees, like other Hymenoptera, have three body segments a head, thorax, and abdomen. There are 1,300 native species of ground-nesting, twig-nesting and parasitic bees found within Arizona. Honey bees pollinate crops, but native bees also have a role in agriculture and they are essential for pollination in natural landscapes. Plants rely on pollinators to reproduce and set seed. For people, this means every third bite of food along with fibers, nutrients and beverages is the result of pollination. Bees provide essential ecosystem services in natural and agricultural landscapes as pollinators of three-quarters of flowering plants and as soil-builders.
