Goka, K., K. Okabe, S. Niwa, and M. Yoneda. Franklin's bumblebee (Bombus franklini) is known to be one of the most narrowly distributed bumblebee species, making it a critically endangered bee of the western United States. [4], Franklin's bumblebee is distinguished from other bumblebees by a solid black abdomen, with yellow anteriorly on the thorax in a U-shaped design. At their peak, colonies may consist of between 50 and 400 workers and the queen (Plath 1927; Thorp et al. … Share. Zayed, A. and L. Packer. 1994). We tag along as one man makes his annual trek to try to find it. Interagency Special Status Sensitive Species Program. This was at the same locality, Mt. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. They may collect both pollen and nectar from vetch (Vicia) and also rob nectar from this plant (P. Schroeder 2006 pers. Subgenus Bombus. The species has a NatureServe Global Status rank of G1, an Oregon state status rank of S1 and a California state status rank of SNR (NatureServe 2009). Why your go-to-market strategy should be industry focused; Dec. 1, 2020. They should still be treated with respect when they are discovered, though. As the colony grows, the workers take over the duties of food collection, colony defense, nest construction, and larval care, while the queen remains within the nest and spends most of her time laying eggs. For Franklin’s bumble bee, the effects of this fungus may have been compounded by insecticide use; loss of habitat; and, given its restricted historic range, a small population size. This gives them the distinction of having the narrowest range of any bumblebee in North America. This profile has been updated by Sarah Foltz, Scott Black, Sarina Jepsen, and Elaine Evans, The Xerces Society. Additionally, increased amounts of UV-B radiation from a reduction in ozone could delay flowering in plants and reduce the amount of flowers that plants produce (National Research Council 2007), while an increase in atmospheric CO2 from global climate change may alter plant nectar production, all of which could have negative effects on the foraging success of bumble bees (reviewed in Davis 2003). Tel: (855) 232-6639 • Fax: (503) 233-6794, Main Office: 628 NE Broadway, Ste. Post-1998, the numbers of populations and individuals of B. franklini have declined drastically, evidenced by intensive and extensive surveys primarily conducted by R. W. Thorp each year from 1998 through 2008 (Thorp 1999, 2001, 2004, 2005b, c, 2008). In: K. Strickler and J. H. Cane (eds.). Franklin’s Bumblebee may be Added to Endangered Species List. Bombus franklini occurs only in the USA. Oxford University Press, Oxford. Schultz, C. B. Inbred populations of bumble bees show decreased genetic diversity and are at a greater risk of decline (Zayed and Packer 2005; Darvill et al. The Franklin's Bumble Bee (Bombus franklini) is a species of concern belonging in the species group "insects" and found in the following area(s): California, Oregon. Franklin's bumble bee was named in 1921 for Henry J. Franklin, who monographed the bumble bees of North and South America in 1912-13.

Archived. Near the end of the colony cycle, reproductives (queens and males) are produced. The Franklin's bee was not put on the endangered species list until very recently, in 2010. There are over 255 species of bumblebees, according to the Integrated Taxonomic Information System (ITIS), so bumblebees can be many sizes. During each of the past 11 years, Dr. Thorp surveyed from nine to 17 historic sites (average 12.3 sites) some visited more than once each year with an average of 29.6 visits to historic sites per year. Stephen, W. P. 1957. Fire suppression can lead to extensive changes in vegetation structure, including degradation and loss of grasslands and herbaceous species as the shrub community matures (Panzer 2002, Schultz & Crone 1998). Pesticide drift from aerial spraying can kill 80% of foraging bees close to the source and drift can continue to be dangerous for well over a mile (Johansen and Mayer 1990). 21-40. Worldwide, bees are facing significant challenges due to habitat loss, pesticide use and climate change. 1997. If its population has indeed reached a critical level, the species will require extensive protection in order to avoid extinction. It uses material from the Wikipedia article "Franklin's bumblebee". Homeowners, community members, school gardeners, farmers—everyone can help (Hymenoptera: Apidae), in montane meadows. 1988. The bumble bees of eastern Canada. No luck.

Sightings increased slightly to 20 in 2002, but dropped to three in 2003. First discovered in 1921, the Franklin’s bumble bee (Bombus franklini) was once found from the valley floor to high elevation peaks throughout its range. Invasive and introduced species: Invasion and dominance of native grasslands by exotic plants is a common issue (Warren 1993, Schultz 1998), and has likely occurred at historic B. franklini locations. Great Basin Naturalist 45: 299-312. The last name is rarely used today and the second name is uncommon.

Bulletin of the Natural History Museum, London (Ent.) During its flight season, from mid-May through September, Franklin’s bumble bee frequents California poppies, lupines, vetch, wild roses, blackberries, clover, sweet pea, horsemint and mountain penny royal. Hobbs, G.A. It was last seen in 2006. Japanese Journal of Applied Entomology and Zoology 44: 47-50 (in Japanese with English abstract). Estimated population… An examination of the theoretical effect of removal of specialist and generalist pollinators on the extinction of plant species concluded that the loss of generalist pollinators poses the greatest threat to pollinator networks (Memmott et al. Molecular Ecology 10: 2095-2099. Franklin’s Bumblebee may be Added to Endangered Species List. Ashland, where the last B. franklini were found in 2003. You can easily recognize them, because they are the only bumble bees flying out there for the moment. 2008 Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? Ecology of species of Bombus Latr. Code, B. H. and L. H. Stephan. Controlled burns, however, could inadvertently threaten this species, and if executed, must be done so only with extreme caution, proper timing, and expert advice. Such species receive no legal protection and use of the term does not necessarily imply that a species will eventually be proposed for listing (ODFW 2009). site management and habitat selection of key species. Proceedings of the Royal Society B 271: 2605-2611. Psyche 34: 122-128. Ecological impacts of introduced honey bees. Extensive surveys from 1998-2008 have demonstrated that there has been a precipitous decline in the number of individuals and localities in the past decade. Research: Monitor, sample, and conduct population estimates of extant populations of B. franklini. It was last seen in 2006. At the end of the colony season the founding queen, all workers and males die and the inseminated hibernating new queens are left to carry on the line into the following year. Thorp’s surveys clearly show the declining population. An annotated checklist of bumble bees with an analysis of patterns of description (Hymenoptera: Apidae, Bombini). 100% Upvoted. It was also abundant in southwest Washington. What makes this species so fragile and close to extinction? Small or inbred populations may also lose resilience to environmental changes, and are at risk of extirpation due to stochastic events such as fire or unusually wet or dry years. Bumble, humble, and dumble all refer to the humming, buzzing, or droning sound made by a bee in flight. Insecticides applied in the spring when bumble bee queens are foraging and colonies are small are likely to have a more significant effect on bumble bee populations than insecticides that are applied at other times of the year (Goulson et al. Ashland and near Copper, OR), one in 1980 (Ashland, OR), two in 1988 (Ashland and Merlin, OR), two in 1989 (Hilt and Yreka, CA), four in 1990 (Ashland, Ruch, Central Point, and Gold Hill, OR), one in 1992 (Ashland, OR), two in 1997 (Roxy Ann Peak near Medford and Ashland Pond in Ashland, OR), and four in 1998 (Roca Canyon in Ashland, Lost Creek Reservoir, and Grizzly Peak near Shale City, OR). University of Kent. Environmental Science, Summer 2015. 1998. New research using a massive dataset found that the insects are far less common than they used to be; in North America, you are nearly 50 percent less likely to see a bumblebee … Males of this species are similar to females, differing as follows: malar space as long as wide, face below antennae with predominantly yellow hair, and tergum 6 with some pale hair laterally. Melanderia 50: 1-12. All bumblebees die in… Landscape level habitat quality has been shown to influence bumble bee species richness and abundance, indicating that isolated patches of habitat are not sufficient to fully support bumble bee populations (Hatfield & LeBuhn 2007; Öckinger & Smith 2007).

This thread is archived. “I already knew (the Franklin’s) had declined by the time I saw that (last) one. Half of the bumble bee species in a new study have seen a more than 50 percent decline in population and distribution. Franklin’s Bumble Bee has the most limited geographic distribution of any bumble bee in North America and possibly the world (Williams 1998). It is found only from southern Oregon to northern California between the Coast and Sierra-Cascade Ranges, in Douglas, Jackson, and Josephine in Oregon and Siskiyou and Trinity counties in California. These include the Morrison Bumblebee, Southern Plains Bumblebee, Franklin’s Bumblebee, Rusty Patched Bumblebee, and the Western Bumblebee. 1990. He saw the population of Franklin’s and another related bee, the western bumblebee, dropping in the early 2000s. Ecological patterns of bees and their host ornamental flowers in two northern California cities. We particularly seek comments concerning: (1) Franklin's bumble bee's biology, range, and population trend… A bumblebee flies near a lavender bush in the International Peace Gardens in Salt Lake City, Utah, on Friday, July 17, 2020.

Fragmented habitats may not support healthy metapopulation structures and may eliminate or decrease source populations of bumble bees for recolonization (National Research Council 2007). Dissertation, University of Washington, Seattle, WA. Most bumblebee species are currently located in central Europe ©Vladimir Sazonov – Adobe Stock.com. 2009. Conduct research aimed at increasing understanding of the pathology and control of Nosema bombi [Microsporidia] and other potential disease organisms (such as Locustacrus buchneri [Acarina] and Crithidia bombi [Protozoa]). Some people might recall dodging flying bumblebees as kids, or finding the bees flitting around flowers in their front yard. Therefore, a further decline in the population of bumblebees could result in higher costs of certain products. Colonies are annual, initiated in spring by solitary, mated queens who emerge out of hibernation to search for appropriate nesting sites. Continued fire suppression not only results in the reduction of bumble bee food plants at these sites, but also renders the habitat susceptible to catastrophic, large scale, and high temperature fires due to increases in combustible fuel loads, tree density, and fire intolerant species (Huntzinger 2003).

Between 1998 and 2005, the number of sightings of Bombus franklini declined precipitously from 94 individuals in 1998 to 20 in 1999, nine in 2000 and one in 2001. Latreille, 1802 (Apidae: Apinae: Bombini). Where does the Franklin's Bumble Bee live? Tolerance of pollination networks to species extinctions. Its entire distribution, including historic populations and recent range extensions (Thorp 1999, 2001, 2004) can be covered by an oval of about 190 miles north to south and 70 miles east to west between 122o to 124o west longitude and 40o 58o to 43o 30o north latitude. Insecticide application on Forest Service managed public lands for spruce budworm has been shown to cause massive kills of bumble bees and reduce pollination of nearby commercial blueberries in New Brunswick (reviewed in Kevan & Plowright 1995). Thorp, R. W., D. S Horning and L. L. Dunning.

Competition from honey bees (Apis mellifera): It has long been assumed, but difficult to demonstrate, that managed honey bee colonies have a negative impact on native bees through competition for floral resources (Sugden et al. Panzer, R. 2002. Canadian 2006). Population plunges almost 90 percent since 1990s; the species is seen as a key pollinator of blueberries, tomatoes and wildflowers OR on 1998 season (submitted 23 Nov 99), Thorp, R. W. 2001. It is known only from a 190-by-70-mile (310 by 110 km) area in southern Oregon and northern California, between the Coast and Sierra-Cascade mountain ranges. Furthermore, the population decreased drastically since 1998. Bumble bees and cuckoo bumble bees of California (Hymenoptera: Apidae). However, researchers have been aware of the rapid decline of the Franklin's bee Fish and Wildlife Service (USFWS 2009). Management: All known Bombus franklini habitat should be protected and managed to include plentiful food (pollen and nectar resources such as Lupinus, Eschscholzia, Agastache, Monardella, Vicia), abandoned rodent burrows in which to nest, and proximity to water sources (lakes, rivers, streams, seeps) for prolongation of flowering season of plant food sources. 67: 79-152. updated at: www.nhm.ac.uk/research-curation/projects/bombus/.

The queen collects nectar and pollen from flowers to support the production of her eggs, which are fertilized by sperm she has stored since mating the previous fall. The Bumblebee Hunter The Franklin bumblebee is so small and hard to track that it's not clear if it's gone extinct. 1985. Females of B. occidentalis are similar to B. franklini in the round faces, and black hair on the face, but differ in having the hair on the vertex black, as opposed to yellow. It is known from Douglas, Jackson, and Josephine counties in Oregon and Siskiyou and Trinity counties in California. Bumble bee colonies are often underground, or in compost, rock walls, hollow logs and under bunch grasses. Molecular Ecology 15: 4375-4386. Competitive interactions between the invasive European honey bee and native bumble bees. 2006. 9 years ago. [5] Females have black hair on their faces and the vertices, with some light hairs mixed above and below their antennal bases, while most similar bumblebee species have yellow. However, the evidence for large-scale range reductions across North America is lacking. The threats to this species are outlined as follows: Disease: The recent declines of Bombus franklini and its close relatives are hypothesized to be primarily due to a selectively virulent strain of the microsporidian Nosema bombi acquired from the commercially reared and closely related European Large Earth Bumble Bee, Bombus terrestris (Thorp 2003, Thorp & Shepherd 2005, National Research Council 2007). 1988. Restoration Ecology 6: 244-252. Biological Conservation 64: 37-49. Pollinator Protection: a Bee and Pesticide Handbook. A federal study details an alarming decrease in the western bumblebee population over the last two decades, which may result in the insect being added to the endangered species list. Queens are responsible for initiating colonies and laying eggs, workers are responsible for most food collection, colony defense, nest construction, and feeding of the young, and males sole function is to mate with new queens produced at the end of the colony season. Thomas Say Publications in Entomology: Proceedings. Thorp, R. W. 2005b. It’s unclear whether the bees might recover. Bulletin of the California Insect Survey 23: viii. Other bumble bees with similar color patterns in the range of B. franklini have the yellow extending back to the wing bases or only slightly beyond and usually have one or more bands of yellow on the middle or slightly behind the middle of the abdomen (most on tergum 4). Queens usually mate with only one male, but males may mate with multiple queens. Species Profile: Bombus franklini. 1998. 2003, Smallidge & Leopold 1997).

Detecting the effects of introduced species: a case study of competition between Apis and Bombus. IUCN. Competition between European honey bees and native bumblebees: resource overlap and impact on reproductive success. In particular, agricultural intensification, livestock grazing, urban development, and road construction can fragment bumble bee habitat into pieces that are too small or too distant to support diverse bumble bee communities (Goulson et al. Sightings decreased from 94 in 1998 to 20 in 1999 to 9 … We recommend against the practice of collecting queen bumble bees as colony reproductive success is … An early switch point results in more males and fewer queens, while a late switch point results in larger colonies, more queens, and fewer males (Duchateau and Velthius 1988). Franklin’s bumblebee is a species once found in a narrow region where California and Oregon meet. Frankie, G. W., R. W. Thorp, M. Schindler, J. Hernandez, B. Ertter, and M. Rizzardi. Thorp, who died at age 85 on June 7 at his home in Davis, had monitored the population closely since 1998, but last saw the bumble bee in August 2006. 2004.

Oregon State College, Agricultural Experiment Station, Technical Bulletin 40, 163pp. Franklin’s bumble bee is easily identified by the extended yellow on the anterior top of the thorax that extends behind the wing bases and forms an … Goulson and Sparrow (2009) found that bumble bees are smaller, and thus less fit, in areas where managed honey bees occur in Scotland. In K. Strickler and J. H. Cane (eds.) Journal of the Kansas Entomological Society 78: 227-246. Report to US Fish and Wildlife Service, Portland, OR on 2004 season (submitted 29 March 2005). VI. Bombus franklini is readily distinguished from other bumble bees in its range by the extended yellow on the anterior top of the thorax which extends well behind the wing bases and forms an inverted U-shape around the central patch of black, lack of yellow on the abdomen, predominantly black face with yellow on the vertex (top of the head), and white at the tip of the abdomen. Hatfield, R. G. and G. LeBuhn. The U.S. FWS's Threatened & Endangered Species System track information about listed species in the United States pp. Two colonies of B. franklini initiated in the laboratory and set out to complete development in the field contained over 60 workers by early September, and probably produced over 100 workers by end of season (Plowright and Stephen 1980).
