A bumblebee is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals.
Bombus fraternus is an endangered species of bumblebee known commonly as the Southern Plains bumblebee. It is native to the United States east of the Rocky Mountains. It is most often encountered in the southern Great Plains and along the Gulf Coastal Plain. This species has been found as far north as New Jersey and North Dakota, and as far south as Florida along the Gulf Coastal Plain into the state of Chihuahua in Mexico. This species was uncommon historically, but having faced declines in population; its estimated abundance is less than 15% of historical numbers.
Parasitellus is a genus of mites in the family Parasitidae which are obligatory parasites of bumblebees. These mites can be found clinging to the carapace, sometimes in large numbers. Mites in this genus hibernate in the deutonymphal stage. In the tritonymph stage they can actively transfer from bumblebee to bumblebee from flowers, where they can survive up to 24 hours. After they arrive in a bumblebee nest, they will moult into adults. Whilst it is not known what factors trigger the mite to molt, in laboratory conditions P. fucorum were found to moult after eating fresh pollen, although overall moulting success was low. They are kleptoparasitic or neutral to beneficial, depending on life stage; females and deutonymphs feed on provisioned pollen, while other stages are predators of small arthropods.
