Besides fibrous material, what physical substrate must *A. manicatum* females seek for nesting cavities?
Answer
Pre-existing holes like abandoned beetle burrows in dead wood.
Successful reproduction for the solitary female Wool Carder Bee depends on fulfilling two concurrent needs: obtaining the woolly fiber for cell lining and securing a suitable structure in which to lay her eggs. Crucially, these bees do not excavate new tunnels themselves. Instead, they are cavity nesters that rely on repurposing existing voids. This includes searching for abandoned burrows previously created by wood-boring beetles within dead wood, or utilizing existing hollow plant stems. This dependence on pre-formed structural habitat means that even areas rich in preferred fiber might not host nesting if suitable, undisturbed dead wood or hollow structures are absent.
