Male green orchid bees can be quickly and easily attracted and observed by soaking a small piece of paper with clove oil and placing it outside. 1/5”  (.21")  (very small). Bi-colored Agapostemons are polylectic -- that is, they feed on a variety of plants rather than specializing on a single kind. The bee shown here, Augochloropsis metallica , is found as far north as Canada and as far south as Texas. Family:   Halictidae  (Sweat Bees) The bee featured here was found feeding on goldenrod in August on a sunlit park trail. One way to tell male silky Agapostemon males from bi-colored Agapostemon males is that the underside (sternum) of a bi-colored Agapostemon's abdomen is distinctly blacker. Scent-robbing and fighting among male orchid bees. The wing membranes are darkened, but transparent. Figure 2. Sure, they all buzz around and collect pollen. Orchids will then affix a pollinarium to the bee which is carried to another orchid of the same species. They are roughly the same size to slightly smaller than a honey bee, usually about 1.3 cm in length. The female bees frequently carry large caches of yellow pollen on their hind legs, as shown in the photos at right. If you wish to use any of the photographs here for educational or other purposes, please read permissions page. Female orchid bees have corbiculae (pollen baskets) on their hind legs, in which they store collected pollen in order to provision their young (Figs. Contents: 1 introduction to hover flies, 2 Bee like hover flies, 3 Bumble Bee like hover flies, 4 Wasp like hover flies, 5 Other hover flies. All rights reserved. According to the National Audubon Society Field Guide to Insects and Spiders, bi-colored Agapostemons work cooperatively; bees entering the nest carrying pollen are given right-of-way over those trying to leave, and multiple bees in the nest work to restore entrance holes as they crumble. They are fast fliers and, when collecting pollen, they alight briefly on a flower before zipping on to the next. The upper part of the male bee's tegula (where the wing joins the body) is metallic green. The Lucifer hummingbird is a rare but beautiful hummingbird in North America. 2004. • Bright, metallic green or green-blue coloring on part or all of the body • Some have white and black striped abdomens, others have green or blue abdomens • Medium body size: 5-11 mm mm There are only three species of this genus in the United States. 1 Introduction to Hoverflies Hoverflies or Syrphid Flies (or Flower Flies, if you prefer American nomenclature) belong to a big family varying from small to large flies. Subgenus:  Agapostemon Genus:   Augochloropsis. Their legs are yellow with with black markings. … Many are easily recognizable due to their beautiful, iridescent green or golden colors, making them favorites of many insect photography hobbyists. Characteristic green metallic coloration, long tongue, brush-like front tarsi, and enlarged hind tibiae are visible. A male Euglossa dilemma photographed from various angles. Identifying Traits:  Bi-colored Agapostemons can be identified by their shiny green heads and thoraxes. Jun 1, 2013 - Hard to photograph, and there are different kinds of Green bees, Metallic Green Bees, green Sweat Bees. Hand characteristics of Females:  Silky Agapostemon females are often confused with the green metallic sweat bees of the Augochlorini tribe featured below on this guide page. Mature nests can contain up to 20 cells. At the top of the bee's hind leg is the segment called the trochanter -- on bi-colored Agapostamon males, this segment is metallic green, as shown here. Males have a boldly iridescent purple throat, green upperparts and flanks, and a dark, forked tail. Different Species of Hummingbirds – An informational resource for learning about the different breeds of hummingbirds. Typically, each species of orchid bee has a complex mutualistic relationship with a corresponding orchid in their native range. The legs of female Augochloropsis metallica bees are green and covered with pale hairs; the end segments of the bees' legs (called tarsi) are dark brown. The bees' nests are sometimes established by a single foundress that dies off during the worker phase, and which is replaced by a single “replacement queen” from the first brood. Hummingbirds are among the smallest types of birds and can only be found naturally in the Americas. National Audubon Society Field Guide to Insects and Spiders, In addition to being efficient pollinators of wildflowers, bi-colored, These stunning bees pollinate a variety of fruit crops, including melons, apples, blueberries, cranberries and blackberries. In such instances, orphaned colonies are considered “parasocial” . Scarab beetle, any of approximately 30,000 species of beetles that are compact and heavy-bodied insects with robustly oval outlines. Sweat bees shown in this guide represent six distinct sweat bee genera that can be grouped roughly by their salient characteristics:  (1)  iridescent green bees (Agapostemon, Augochlora, Augochloropsis and Augochlorella); and (2) bees that are dark in color, usually with striped abdomens (Halictus and Lasioglossum). These bees are a highly important group of  wild pollinators, responsible for the pollination of an impressive range of  commercial crops --  among them squash, legumes, sunflowers, watermelons, apples, cranberries, blueberries, strawberries, tomatoes and peppers, to name but a few. Though males lack corbiculae, they have characteristic enlarged hind tibiae (Fig. Their iridescent blue, blue-green, green or violet reflections, together with their robust cylindrical body render them instantly recognizable; they are occasionally jet-black. All orchid bees are native to the New World tropics, from Mexico throughout Central and tropical South America. Augochlora  pura have brilliant green heads, thoraxes and abdomens covered with minute whitish hairs. The tegula ofAugochlorella aurata is reddish, while that of Augochlora pura is dark and oval. As with most bees in Florida, females possess a stinger and males do not. Specimens of one species of this group, Euglossa dilemma, commonly known as the green orchid bee, were collected in Broward County, Florida in 2003 by entomologists working with the USDA fruit fly monitoring program. Update! Insect Detection. Bees of the augochlorini tribe tend to be smaller generally than the agapostemons shown above. This helps distinguish males of this species from the male Agapostemon texanus, whose abdomen has metallic or blue-green highlights. (The single sweat bee genus, Augochlora, Augochloropsis and Augochlorella). Close-up of the vertex (top of head) and thorax of an Augochlora pura. But they’re often confused with bumblebees, who don’t nest in wood or become problem… Identifying Traits:   The heads, thoraxes and abdomens of female silky Agapostemons are solid iridscent yellowish-green. Augochlorella aurata sweat bees nest in partly-bare areas of flat or gradually sloped ground. (4) The flight pattern of the female silky Agapostemon is also distinctive -- a jagged series of fast figure eights -- and it tends to come to rest on the tops of the flowers. Male orchid bees exhibit a peculiar behavior of collecting fragrant volatile compounds from their environment. This behavior is presumably what has led to the complex interaction with species-specific orchids in their native ranges. Traits helpful in distinguishing silky Agapostemons from other green sweat bees are noted below and in the photos at right. (See photos in the above entry on bi-colored Agapostemons.) The green female bee was discovered nectaring on wild carrots in Stone Barns' cut-flower fields in early September. Minnesota now has a state bee as well as a state insect. Pollination by euglossine bees. This iridescent bee is found on the eastern side of North America. Fighting and robbing fragrance stores from competing males has been observed in nature. Following a line that runs from Tampa to West Palm Beach and south, the potential range extends tothe entire southern tip of the Florida Peninsula. In the park, they are likely to be spotted foraging  on dogbane, fleabane, mountain mint, wild roses and goldenrod. These bees are far less common in the park than the other green metallic sweat bees shown on this guide page. Dressler RL. Order:   Hymenoptera The bees seem particularly interested in an old, decomposing piece of pinewood siding rife with wood decay fungi. Augochloropsis bees are believed to have originated 16 million years ago and to have entered temperate North America 4 million years ago. Agapostemon virescens -  2/5"  (medium-small). They are distinguished from other beetles by their unusual antennae, each of which terminates in three flattened plates that fit together to form a club. This arrival was likely from a nest imported from Mexico concealed within a wooden structure such as a pallet. Silky Agapostemons also visit a multitude of garden flowers and wildflowers, among them rhododendrons, catmint, asters, yarrow and goldenrod. Live adult Halictid bees photographed in the wild at various North American locations. In the summer, the bees can be seen visiting orange butterfly milkweed, wild phlox and goldenrod in sunny areas of the park and pollinating squash and a variety of flowers in Stone Barns' vegetable fields and gardens. Females carry pollen on their hind legs and have distinctive black mandibles. Augochloropsis metallica are larger than Augochlora pura and Augochlorella aurata and have broader abdomens that bell outward near the bottom. Note that the upper portion of each of the male bee's legs is metallic green; the lower portions are pale. Distinguishing among green metallic sweat bees: A feature common to members of the Augochlorini tribe is that they have hind tibia that are shorter than their combined tarsal segments. Taxonomy of Augochlorella Aurata  Sweat Bees, An Augochlorella aurata with coppery-pink coloration, An Augochlora pura sweat bee emerging from under the bark of a fallen tree, Augochloropsis metallica –  .35”  (small). Male Agapostemon sp. Orchids will produce scents that attract males of a particular species of bee that is the right size and shape to pollinate them. Species:  Agapostemon virescens, All photos (c) 2014 - 2016 Sharp-Eatman Nature Photography, The abdomens of male bi-colored Agapostemons have yellow stripes. Note that the last few segments on the end of the bee's sternum (the underside of its abdomen) are black. In the first spring “foundress phase,” the bees construct an underground nest and provision it for 6-8 male and female offspring. Males have predominantly green legs, and pale yellow tarsi. Only 1 available and it's in 2 people's carts. Silky Agapostemons are solitary and build their nests in the ground. Augochlora pura bees can be distinguished from other green metallic bees in part by minute inspection of three traits:  (1)  an Augochlora pura bee's tegulae (where the wings attach) are dark and oval in shape; (2) the marginal cell of an A. pura bee's wing is truncate; and (3) the female bee's face has distinctive "epistomal lobes". Solitary invasive orchid bee outperforms co-occurring native bees to promote fruit set of an invasive. Augochlorella aurata bees are broad generalist pollinators that visit a seemingly endless range of wildflowers. The sting itself is less painful than that of a honey bee, though unlike honey bees they can sting repeatedly. The pink male bee shown here was found feeding on goldenrod in mid-August on a sunny park trail. Figure 1. These bees appear in the park's gardens, meadows and woodland paths in mid-spring and remain through mid-October, foraging for nectar on such plants as coneflowers, coreopsis, mountain mint, Joy Pye weed, goldenrod and New England asters. The wings are clear with light brown veins, and the legs and antennae are black. These unusual structures have a hole on the outer side, which provides access to the spongy compartment within. On that bee, the trochanter is often yellow or mostly yellow (although it may appear metallic as well.) Aussie Bee > Native Bee Identification Guide > Native Bee Photo Gallery. According to Charles D. Michener’s The Social Behavior of the Bees, the tribe Augochlorini consists of bees that are typically brilliant green (but sometimes purple, blue, brassy, red or black); and that live predominantly in Central and South America. Orchid Bees Euglossa is the scientific name of the orchid bees. Skov C, Wiley J. Augochlorella aurata Tribe:   Augochlorini, A female Augochlora pura with her legs laden with red pollen. To stay warm, the females dig downward into the earth from the lowest parts of their nests. Here are the different species of Hummingbirds and their […] © Copyright 2014-2016 Paula Sharp and Ross Eatman, unless otherwise noted. (1)  Augochloropsis  metallica's pronotal lobe (located at the front of the thorax) has a pronounced ridge. Their looks are similar to native Florida sweat bees, or halictids, with a few major differences. Family:   Halictidae  (Sweat Bees) Then I started to wonder if it is a bee at all. 'Iridescent Green Bee' - A limited edition art piece by Jessica Albarn. In addition to being efficient pollinators of wildflowers, bi-colored Agapostemons are key pollinators of sunflowers and legumes. In the case of green orchid bees, this role is not entirely known in its naturalized range in Florida. Order:   Hymenoptera Male bees have an enlarged hind tibia with a hole providing access to the spongy compartment which acts as storage for fragrant compounds collected from its environment. Order:   Hymenoptera They are documented pollinators of blueberries, caneberries and members of the melon and squash families. (3) The Xerces Society's Guide to Attracting Native Pollinators notes that the easiest way to tell female Agapostemons from the Augochlora pura bee directly below is to look at the rear of the thorax:  the Agapostemon's is flat and edged by a curved ridge; the Augochlora pura bee's, by contrast, is rounded and ridgeless. Figure 4. Apidologie 35: 283-291. Photographs by Aaron Mullins, University of Florida, Ft. Lauderdale Research and Education Center. Female Agapostemons' abdomens are striped with bands of white hairs. Dozens of other Augochlora pura nested around her in the same log, looking like living emeralds scurrying in and out of the bark. 1990. Some, like the carpenters, can become pests, drilling holes in wooden building materials to make nests. Augochlorella aurata social behavior shows flexibility, however. The orchid bees are all members of the family Apidae, and the tribe Euglossini, represented by five genera. They're most commonly found in rainforests ranging from Mexico to southeastern Brazil, but recently the bee has made her way up to Florida and decided to stay. Males tend to fly more slowly and rest longer on flowers, looking for mates. Photographs by Aaron Mullins, University of Florida, Ft. Lauderdale Research and Education Center. These bees tunnel under the bark of fallen trees in woodland areas. The Ruby-throated Hummingbird and Rufous Hummingbirds are amongst the most common hummingbirds in the United States. Can they be blue as well as shades of green? Pemberton and Wheeler (2006) provide a comprehensive list of important plants known to be visited by Euglossa dilemma in Florida. They are one of a few species of bees that feed on the nectar of native American white water lilies, which bloom in the park's Swan Lake during the summer. Blue orchard bees are about the same size as a honeybee but there are a few key points that help you tell them apart. Augochlorella aurata sweat bees are the smallest of the three species of the tribe Augochlorini  found in Rockefeller State Park Preserve. Subfamily:   Halictinae Sweat bees are also essential pollinators of native flora, appearing in all seasons in New York on an extensive array of flowering plants found in woodlands and fields. 3a). Genus:   Agapostemon (Metallic Green Bees) Fertilized females from the fall-spring generation over-winter from late fall until early spring. A male silky Agapostemon has yellow spots on the sixth segment of its sternum. Females carry  pollen on their hind legs. Entomology Section. Male bi-colored Agapostemons may be tricky to differentiate from  male Agapostemons of other species. In his seminal work, The Social Behavior of the Bees, the renowned entomologist Charles D. Michener wrote extensively on the nesting behavior and life cycle of Augochlorella aurata (known then under the name Augochlorella striata).
