Two-spotted bumble bee

Two-spotted bumble bee

Bombus bimaculatus

A species of Bumble bees

The name of two-spotted bumble bee (Bombus bimaculatus) comes from the two yellow spots found on its abdomen. Where other bees are on the decline, this one's population remains stable. For the first day of a young male's life, they are unable to fly. As a result, they pump their abdomens against the larva in order to generate heat flow.

Life Cycle of Two-spotted bumble bee
Egg The embryonic phase of two-spotted bumble bee consists of small, oval-shaped eggs, usually pale in color. These eggs are laid in secure locations where they remain until hatching.
Larva Upon hatching, the two-spotted bumble bee enters the larval stage, characterized by a worm-like appearance. They lack wings and have a soft body primarily focused on feeding and growth.
Pupal The pupal stage marks a period of transformation. Here, the two-spotted bumble bee is encased in a protective cocoon or cell and undergoes significant morphological changes internally.
Adult Emerging from the pupa, the adult two-spotted bumble bee’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How and Where Can You Find Two-spotted bumble bee at Different Life Stages
Larva Two-spotted bumble bee larvae are located within underground nests or occasionally above ground in cavities. To find them, look for their nests in the soil, close to flowering plants, and inspect the chambers with caution.
Pupal Two-spotted bumble bee pupae remain in the nest in a cocoon. Locating the nest, often buried in the ground, is key to finding this stage. Exercise great care when digging in known nesting sites to avoid damaging the colony.
Adult Two-spotted bumble bee adults can be found on or near flowers as they forage for nectar and pollen. To find them, visit gardens, meadows, or areas with flowering plants during their active hours, observing flowers known to be preferred by two-spotted bumble bee.

Toxic to Humans

Two-spotted bumble bee, a species of bumblebee, possesses a defense mechanism involving a sting that can inject venom into potential threats, including humans. The venom contains mild neurotoxins that may cause localized pain, swelling, and redness upon envenomation. Typically, the impact is minimal, causing short-term discomfort. In rare severe cases, individuals with heightened sensitivity could experience more pronounced symptoms, but such instances are not common among the general population.

Does the Two-spotted bumble bee sting humans?

Two-spotted bumble bee typically sting only in defense of themselves or their colony. Stinging is a last resort, often resulting from human provocation. Only the female two-spotted bumble bee can sting, as males lack a stinger. The act poses no physical harm to the animal. However, human reactions can range from mild discomfort to severe allergic responses.

Rectangle
Does the Two-spotted bumble bee cause allergies?

Two-spotted bumble bee, during its adult stage, can potentially cause allergies in a small subset of humans through its sting, which delivers toxins. The severity of allergic reactions may range from mild to severe. Individuals affected might experience common symptoms such as swelling or hives. Given the degree of risk is variable, those with heightened sensitivity should proceed cautiously around two-spotted bumble bee.

Eulaema meriana
Eulaema meriana

Eulaema meriana resembles a bumblebee in appearance and is covered in short dense hairs. At first glance Eulaema bees look like large bumblebee queens. They are relatively large bees with faint metallic colorations. The head of the bee is black, and the thorax brownish black with a large, glossy black scutellum. Their abdomen is black with three transverse pale yellowish bands on the anterior half, and the posterior third is reddish brown. E. meriana also possess membranous wings that are dark at the base and paler at the tips. The legs are black and the tibia of the hind legs are much thicker. Males possess hollows on their hind legs, while females have pollen baskets. In general, the species have long tongues that are thought to be an evolutionary adaptation that favors nectar collection. The large body size is thought to allow the bees to fly in cooler, rainy conditions and continue foraging. It has also been suggested that the larger body size can help them forage for longer distances.
