Hair on top of head (= vertex) yellow. 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.

Report to US Fish and Wildlife Service, Portland, OR on 2005 season (submitted 7 November 2005). 2006. For example, Kevan (1999) found that herbicide applications have reduced the reproductive success of blueberry pollinators by limiting alternative food sources that can sustain the insects when the blueberries are not in bloom. Subgenus Bombus. However, researchers have been aware of the rapid decline of the Franklin's bee 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 … CDFA. It is listed as critically imperiled by the IUCN Red List of endangered species (IUCN 2009) and the Red List of Pollinator Insects of North America, produced by the Xerces Society for Invertebrate Conservation (Thorp 2005a).

Franklin’s bumblebee is a species once found in a narrow region where California and Oregon meet. u/b0b0tiken. Robbin Thorp has also theorized that the decline of the Franklin’s bumble bee population could also be due to a fungus that was brought in unintentionally into the country with a shipment of bees from Europe.

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. 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). Wicwas Press, Cheshire, Connecticut. At their peak, colonies may consist of between 50 and 400 workers and the queen (Plath 1927; Thorp et al. Conservation Biology 16 (5): 1296-1307. Ecological patterns of bees and their host ornamental flowers in two northern California cities. Some of our U.S. bumblebee species are imperiled. 1996; Butz Huryn 1997). A federal review of existing data unveils an alarming trend for the western bumblebee population, which has seen its numbers dwindle by as much as 93% in the last two decades. BURNS: It's not just the Franklin's bumblebee population that's crashed. Thorp’s surveys clearly show the declining population. No individuals were found in 2007 or 2008. Bumble bee colonies are often underground, or in compost, rock walls, hollow logs and under bunch grasses. Thorp, R. W. 2003.

Elevations of localities where it has been found range from 540 feet (162 m) in the north to above 7800 feet (2340 m) in the south of its historic range. These and other pesticides may be translocated through plants into the nectar or pollen. Although the very large size of the queens suggests that the dispersal ability of this species may be greater than that of other bumble bees within its range, the patchy distribution of its remaining habitat might hinder dispersal made necessary by climate change.

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). Franklin's bumblebee is known to collect nectar and pollen from several wildflowers, such as lupine, California poppy, and horsemint, which causes it to be cl… He didn’t see a single one. 1983); a few individuals have also been encountered in October (Southern Oregon University Bee Collection records). If its population has indeed reached a critical level, the species will require extensive protection in order to avoid extinction. 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). Semi-natural grasslands as population sources for pollinating insects in agricultural landscapes. Natural Resources Canada, Canadian Forest Service, Science and Sustainable Development Directorate, Ottawa, Ontario, Canada. There are currently no federal regulations that limit the interstate transport of bumble bees even outside their native range (Flanders et al. NatureServe, Arlington, Virginia. Creature Profile. 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. Thorp, R. W. 2005b. 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).
