native masked bee nesting alone in soft clay banks
- Size
- Length: 6–10 mm
- Lifespan
- 1–2 years
- Diet
- Adults feed on nectar and pollen from small-flowered native plants. Larvae fed pollen and nectar. Nest in hollow stems, old beetle holes in dead wood or pre-existing cavities.
- Habitat
- Forest margins and gardens, often nesting in hollow stems of plants or old beetle holes in dead wood. The urban apartment-dwellers of the bee world.
- Range
- Throughout North and South Islands in native forests, gardens and scrublands. Most common in lowland areas with diverse native flowering plants and available nesting cavities.
- Endemism
- Endemic
- Main Threats
- Habitat loss from forest clearance and removal of dead wood. Competition from introduced honey bees and bumblebees for nectar. Pesticide use in gardens and farmland. Loss of nesting cavities.
- Population
- Small, slender and almost hairless, these bees are often mistaken for tiny wasps. Highly efficient pollinators of small-flowered native plants.
- Conservation Status
- Not Threatened
An intricate mask of yellow or white facial markings defines the native masked bee. This sleek, solitary specialist of the New Zealand bush has a slender, wasp-like anatomy nearly devoid of external hair. Unlike the robust, fuzzy bees typically found in European gardens, these indigenous residents possess an internal transport system.
They lack pollen baskets on their hind legs. Instead, they swallow nectar and pollen to carry it within a specialised crop before regurgitating it back at the nest. This hidden sophistication allows them to navigate the dense understory with an aerodynamic efficiency that belies their vital role as primary pollinators of our native flora.
These bees are the cellophane-makers of the invertebrate world, exhibiting a level of precision engineering that rivals modern chemistry. To protect her developing larvae from the damp and fungal spores of the New Zealand climate, the female lines her nest, often a recycled borer hole or a hollow stem, with a liquid secretion from a specialised gland. This substance quickly hardens into a waterproof, silk-like membrane remarkably similar to modern cling-film.
This life cycle is a definitive sign of a complex forest, where every architectural nook of a dead tree becomes a high-tech nursery. They represent the interior designers of the bush, proving that true resilience is a matter of creating one's own barriers against an unpredictable world.
Not threatened, native masked bees are essential for the survival of specialised plants like Acca sellowiana and various native hebes. They serve as a primary link in the hidden sophistication of the forest, illustrating how the most delicate-looking residents are often the most technologically advanced.
To encounter a masked bee darting into a tiny crevice is to witness a survivor that has mastered the art of precision engineering, a creature that proves that the most enduring successes are those built from the inside out.
