Mckay'S Western Bumble Bee

bombus mckayi

McKay'S Western Bumble Bee (Bombus mckayi) is a highly resilient and vital pollinator native to the cold, high-latitude environments of northwestern North America. Once classified as a northern subspecies of the Western Bumble Bee, genetic and morphological studies have elevated it to a distinct species. This robust, furry bee is superbly adapted to the subarctic climate, emerging early in the spring to forage when temperatures are too low for most other insect species. By visiting a wide variety of native wildflowers, they play an indispensable role in maintaining the health and biodiversity of northern ecosystems.

生息地: Found in northern boreal forests, subalpine meadows, and shrubby tundra edges across Alaska, Yukon, and northern British Columbia.

外見

This species has a stout, robust body covered in dense pile. It features a black head with yellow hairs on the front of the thorax, a distinct black band between the wings, and a bright yellow band on the second abdominal segment (T2). The distinguishing field mark is the tip of the abdomen (T5), which is pale white or soft cream-colored. Queens are notably larger, measuring up to 2.1 centimeters in length, while workers and males are smaller but share the same distinct tri-colored black, yellow, and white banding pattern.

おもしろい事実

It was originally classified as a subspecies of the Western Bumble Bee but was given full species status following DNA analysis.

McKay's Western Bumble Bee is uniquely adapted to survive at high latitudes and can continue foraging under dense cloud cover and light drizzle.

Their extremely thick body hair allows them to trap solar radiation, effectively turning their own bodies into miniature solar-heating units.

特殊能力

The bee grabs a flower and rapidly vibrates its flight muscles, releasing stubborn pollen from tube-like anthers that other insects cannot access.

It can violently shiver its flight muscles to generate internal heat, allowing it to fly and forage in temperatures close to freezing.

Its exceptionally thick, dense coat of hair traps heat close to its body, acting as a natural winter coat in harsh northern climates.

サイズと詳細

体重: 1.2e-304+ kg
Top Speed: 15 km/h

食性と食事

Feeds primarily on sugar-rich nectar for daily flight energy and collects nutrient-dense pollen to feed and raise the colony's larvae.

年齢による違い: Adults feed almost exclusively on liquid nectar for immediate energy, whereas developing larvae are fed a protein-rich paste of pollen and nectar.
