What actionable, low-tech conservation measure directly supports the nesting survival of solitary *Hylaeus* specialists?
Answer
Protecting areas containing sufficient amounts of native, dead, or woody debris
Because *Hylaeus* bees are solitary, they do not form large social hives; instead, they nest individually within pre-existing cavities found in materials such as dead wood or hollow plant stems. Therefore, a direct and effective conservation strategy involves preserving and managing landscapes to ensure an adequate supply of this necessary nesting substrate. Protecting native, dead, or woody debris supports the continuity of their life cycle by providing safe locations for females to provision cells for the next generation of endemic specialists without the need for complex, high-tech interventions.
