Life Cycle of Hawaiian Yellow Faced Bee
The of the Hawaiian Yellow Faced Bee is a fascinating journey that begins with the egg stage and progresses through the larval, pupal, and adult stages. Each stage plays a vital role in the development and survival of this unique species.
Egg Stage
At the start of the , a female Hawaiian Yellow Faced Bee carefully selects a suitable nesting site to lay her eggs. These nesting sites can vary from underground burrows to hollow plant stems or even small crevices in rocks. Once the site is chosen, the female bee constructs individual cells within the nest using a combination of wax and plant materials.
Within each cell, the female bee deposits a single egg. These tiny, oval-shaped eggs are white in color and about the size of a grain of rice. The female bee then seals the cell, protecting the egg from potential predators or harsh environmental conditions. As the egg stage progresses, the embryo inside the egg undergoes development, preparing for the next stage of its life.
Larval Stage
As the Hawaiian Yellow Faced Bee egg hatches, it enters the larval stage. The larva, commonly referred to as a bee grub, is a legless and worm-like creature. It is entirely dependent on the provisions left behind by the female bee in the cell. These provisions consist of a mixture of pollen and nectar, which serve as the larva’s sole source of nutrition.
The larva actively feeds on the provisions, growing in size and strength. It undergoes several molts, shedding its outer layer to accommodate its growth. This stage is crucial for the development of the bee’s internal structures, such as its digestive system and reproductive organs. The larval stage typically lasts for several weeks, during which the bee grub continues to consume the stored provisions.
Pupal Stage
After the larval stage, the Hawaiian Yellow Faced Bee enters the pupal stage, also known as the cocoon stage. This is a transformative period where the larva undergoes a remarkable metamorphosis to become an adult bee. Inside the sealed cell, the larva spins a silk cocoon around itself, providing protection and support during this critical phase.
Within the cocoon, the bee undergoes a complete reorganization of its body, undergoing dramatic changes in form and structure. Wings, legs, and other external features begin to develop and take shape. This stage is akin to the caterpillar transforming into a butterfly. It is a time of rapid growth and transformation, as the bee prepares to emerge as a fully developed adult.
Adult Stage
Finally, after completing its transformation, the Hawaiian Yellow Faced Bee emerges from the cocoon as an adult. This stage is characterized by the bee’s ability to fly, reproduce, and fulfill its role as a pollinator in its ecosystem. The adult bee has a unique set of physical characteristics, including its striking yellow facial markings, which distinguish it from other bee species.
As an adult, the Hawaiian Yellow Faced Bee’s primary purpose is to gather nectar and pollen from flowers for nourishment. During this stage, the bee engages in foraging patterns, visiting various plants in search of food sources. It plays a crucial role in pollination, transferring pollen from one flower to another, facilitating the reproduction of native plants and ensuring the survival of these ecosystems.

Behavior of Hawaiian Yellow Faced Bee
Solitary Nesting Behavior
The Hawaiian Yellow Faced Bee, also known as Hylaeus anthracinus, exhibits solitary nesting . Unlike social bees such as honeybees, which live in colonies with a queen and worker bees, the Hawaiian Yellow Faced Bee prefers to live and nest alone. Each female bee excavates her own nest in various natural substrates, including dead wood, plant stems, and even crevices in rocks.
During the nesting process, the female bee constructs individual brood cells within her nest. These brood cells serve as protective chambers for the bee’s eggs and developing larvae. The female bee meticulously provisions each cell with a mixture of nectar and pollen, which will serve as food for the developing larvae.
Once the brood cells are provisioned, the female bee lays a single egg inside each cell. She seals the cell with a waterproof cap, created from plant resins or other suitable materials. This cap protects the developing larvae from moisture and predators.
The solitary nesting of the Hawaiian Yellow Faced Bee is crucial for its survival and reproductive success. By nesting alone, each female bee ensures that her offspring have access to abundant resources and are not in competition with other bees for food or nesting sites.
Foraging Patterns
The foraging patterns of the Hawaiian Yellow Faced Bee are influenced by its specialized relationship with native plants. This bee species has co-evolved with the unique flora of Hawaii and has developed specific preferences for certain plant species.
The Hawaiian Yellow Faced Bee primarily forages on native flowering plants, such as the ‘ōhi’a lehua tree (Metrosideros polymorpha) and the native lobelia species (Lobelia spp.). These plants provide a rich source of nectar and pollen, which are essential for the bee’s survival and reproduction.
During foraging, the bee collects nectar from the flowers using its long tongue-like structure called a proboscis. This tube-like mouthpart allows the bee to access the nectar deep within the flower. While feeding, the bee inadvertently picks up pollen grains on its body, which then get transferred to the stigma of other flowers, facilitating cross-pollination.
The foraging patterns of the Hawaiian Yellow Faced Bee are not random but rather follow specific routes or circuits within its foraging range. These circuits allow the bee to efficiently visit multiple flowers of the same plant species, maximizing its foraging efficiency and reducing unnecessary energy expenditure.
The bee’s foraging is not only important for its own survival but also plays a crucial role in pollinating native plants. By transferring pollen from one flower to another, the Hawaiian Yellow Faced Bee facilitates the reproduction of these plants, ensuring the continuation of their populations and the overall health of the ecosystem.

In return, the bee obtains nectar as a food source, ensuring its survival.
Additionally, the Hawaiian Yellow Faced Bee contributes to the pollination of other native plants such as the mamane tree, which is an important component of the dry forest ecosystem in Hawaii. By transferring pollen from one flower to another, the bee facilitates the fertilization process and enables the production of seeds and fruits. This, in turn, supports the growth and regeneration of native plant populations.
Predators and Parasites
While the Hawaiian Yellow Faced Bee has evolved effective pollination strategies, it also faces challenges from various predators and parasites. These can have significant impacts on the population dynamics and survival of the bee.
One of the primary predators of the Hawaiian Yellow Faced Bee is the invasive yellowjacket wasp. Originally introduced to Hawaii, this aggressive wasp species preys upon the bees, raiding their nests and consuming both the adult bees and their larvae. The yellowjacket wasp poses a significant threat to the bee population, as it competes for resources and directly reduces their numbers.
Another challenge comes from the parasitic mites that infest the Hawaiian Yellow Faced Bee colonies. These mites, such as the Varroa mite, feed on the bees’ hemolymph, weakening their immune systems and making them more susceptible to diseases. The presence of these mites can lead to the decline of entire bee colonies and further exacerbate the the bees face.
To mitigate these , conservation efforts focus on controlling the populations of invasive predators and implementing measures to limit the spread of parasitic mites. By reducing the impact of these , the Hawaiian Yellow Faced Bee has a better chance of thriving and fulfilling its crucial role as a pollinator in Hawaii’s ecosystems.
In summary, the Hawaiian Yellow Faced Bee engages in important interactions with other species, particularly in the context of pollination. Its relationships with native plants enable the transfer of pollen, facilitating reproduction and the production of seeds and fruits. However, the bee also faces challenges from predators like the yellowjacket wasp and parasites such as mites. Conservation efforts aim to protect the bee from these to ensure its continued role as a vital pollinator in Hawaii’s unique ecosystems.
