Two bee species have recently been declared as endangered by the US Fish and Wildlife Service. (Reporting by Steve Gorman in Los Angeles; Editing by Sandra Maler). Bees pollinate flowers while they forage for nectar and pollen, using their proboscis to reach down into the flower and suck out the nectar. The use of chemical sprays in agricultural farming eliminates the insect’s natural nectar sources. There are many different reasons these bees are endangered, including habitat loss, pesticides, and other anthropogenic causes.
Wasp nests are papery and made from wood fiber, compared to the waxy hives of bees. Changing seasonal trends in temperature, water availability, and season length can have significant impacts on flowering plants. This will seriously affect the human diet. Freshwater will start drying up as well as, as there will be less trees for water retention to occur. Bees are the primary initiators of reproduction among plants, as they transfer pollen from the male stamens to the female pistils. Both wasps and bees are classified in the order Hymenoptera (along with ants.) Wild bee population should also be conserved to manage some colony disorders.
Nonnative bees compete with native bees for resources and transmit disease to native bee populations. Simply, without these powerful pushers of pollination, flowers, plants, crops, and trees all fail to flourish. The western honey bee (Apis mellifera) is the most important pollinator for agriculture. Four have already decreased nearly to extinction while suffering range contractions of up to 87%.
However, human impacts are a serious threat to many species of bees.
Some species were added to the endangered list in 2017 (seven species of Hawaiian yellow-faced bees) and 2018 (The rusty-patched bumblebee, Bombus affinis) so as to protect and revive their numbers.

Systemic insecticides contain toxic ingredients such as clothianidin and thiamethoxam, which are associated with memory impairment, loss of sense of direction, brain metabolism and eventually death. Since the end of World War 2, the use of pesticides in agriculture has increased exponentially. In 2016, the seven Yellow Faced Bee Species which are native to Hawaii were declared endangered & protected under the Endangered Species Act. The cultivation and international transport of bumble bees for greenhouse and other agricultural pollination has hurt native bumble bees. Though honey bee populations have experienced substantial changes over the last few decades, they are not endangered. Hedges, flowers, trees are mowed down to make room for crop fields, or animal rearing space. Without bees in the ecosystem, the plants they pollinate will likely not survive.
