Appearance of Two form bumble bee
Bombus bifarius has a relatively small body size ranging from 8 to 14 mm (0.31 to 0.55 in) for workers and 15–19 mm (0.59–0.75 in) for queens, with short, even hair covering their bodies. B. bifarius individuals express multiple color polymorphisms; however, many similarities exist between these color variants. Hair on the faces of B. bifarius individuals is usually yellow or white in color and sometimes exhibits black coloration on the top of the head. In at least the lowermost third of the thorax, there is also black coloration. The hindlegs and pollen baskets can be a brownish-orange or black, depending on whether metasomal tergite (abdominal segment) 3 is black or not. In the nominate color variant, metasomal tergites 2 and 3 are red, while in the nearcticus color variant, metasomal tergites 2 and 3 are black.
Sexual dimorphism Males are similar in size to female workers, ranging from 8 to 13 mm (0.31 to 0.51 in). Their eyes are also similar in size and shape to those of their female counterparts, which is in direct contrast to other species of bumblebee. Colorations on their bodies are similar to those of workers and the queen; however, T3 and T6 are most frequently black in males and can vary between black, red, and yellow in workers and queens.
Nests Bombus bifarius nests are made underground or on the surface of the ground. These nests are often small and are made up of one singular open chamber. B. bifarius can also make their nests in abandoned rodent nests.
Diet Bombus bifarius forages for pollen and nectar from the following plants: Aster, Centaurea, Chrysothamnus, Cirsium, Epilobium, Ericameria, Haplopappus, Helenium, Lupinus, Melilotus, Monardella, Penstemon, Ribes, Senecio, Solidago, and Symphoricarpos.

How to Identify Two form bumble bee?

Life Cycle of Two form bumble bee
Egg The two form bumble bee begins as a small, oval-shaped egg. It is usually white or cream in color and laid in clusters. The egg stage is relatively static, with no locomotion or feeding.
Larva Upon hatching, the two form bumble bee larva is worm-like with a soft exoskeleton. It is voracious, feeding constantly to grow. It periodically molts its exoskeleton to accommodate its increasing size.
Pupal After reaching a sufficient size, the two form bumble bee forms a pupa. This protected stage exhibits no feeding as the creature undergoes transformation. Its shape is distinct, commonly resembling a rounded capsule.
Adult Emerging from the pupa, the adult two form 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.

Habitat Preferences of Two form bumble bee Through Different Life Stages
The two form bumble bee is often found in temperate climates, with queens emerging from hibernation in early spring seeking for well-drained, fluffy soils to establish underground nests. The larvae grow in wax-covered cells with ample pollen and nectar resources. Worker bees commonly forage among flowering plants in meadows, gardens, and forest edges. As these workers mature, they venture to similar floral landscapes to continue the pollination cycle. Males typically disperse from the nest upon maturity to mate, frequently seen hovering around tall grasses or woody shrubs, finding flowers nearby. To search for the two form bumble bee in various stages, scout for nest entrances in loose soil during spring, observe blooming vegetation for foraging workers, and examine sunny, open areas for flying males.

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.
