Abeilles indigènes nichant dans les tiges
multiple genera (Ceratina, Hylaeus, Osmia, etc.)
Abeille
Entrée par groupe fonctionnel pour les abeilles solitaires indigènes qui passent l'hiver dans les tiges creuses des plantes. C'est la raison pour laquelle NC State Extension recommande systématiquement, pour Echinacea, Rudbeckia et de nombreuses autres vivaces indigènes, de couper les tiges mortes à 12-24 inches de hauteur et de les laisser debout plutôt que de tout raser au niveau du sol.

Plantes à nectar · 2
The Lady Bird Johnson Wildflower Center flags Camassia quamash as a plant of special value to native bees, and NC State Extension lists the flowers as "bee friendly." Used here as the closest available native-bee entry; common camas is a spring nectar and pollen source rather than a stem-nesting substrate.
The Lady Bird Johnson Wildflower Center flags special value to native bees and lists it as a nectar source; manzanitas are an important late-winter/early-spring nectar plant for native bees.
Plantes à pollen · 3
The Lady Bird Johnson Wildflower Center flags special value to native bees and a role in conservation biological control; the dense spring thyrses are a heavy pollen and nectar source.
The Lady Bird Johnson Wildflower Center flags Penstemon eatonii as of "Special Value to Native Bees" (a Xerces Society pollinator-value flag).
Willows (Salix) are documented hosts for a suite of pollen-specialist native bees that emerge in early spring to coincide with willow bloom; pussy willow is one of the earliest available sources.
Plantes abri · 15
Elderberry stems have soft pith that stem-nesting native bees can excavate; the Lady Bird Johnson Wildflower Center flags the species as providing nesting materials and structure for native bees.
Standing clumps and stems provide nesting materials and overwintering structure for native bees.
NC State documents stem-nesting bee use of dead Liatris stems through winter. Cut back to 12-24 inches in late fall and leave standing through the cold season.
Dill's hollow, pithy stems are the kind of standing structure stem-nesting native bees use when left over winter; this is the general habit of hollow-stemmed herbs rather than a dill-specific record in the cited sources.
NC State Extension notes native bees nest in the dead, hollow stems of roses; leaving some cut canes standing provides nesting habitat.
Dense clumps and standing stems through winter provide overwintering habitat for ground-nesting native bees.
Native bees nest in the dead, hollow stems through winter; the load-bearing reason NC State Extension advises cutting back stems to 12-24 inches in late fall rather than clearing flush to the ground.
Native bees nest in the dead, hollow stems of roses; leaving some cut canes standing can provide nesting habitat, as it does for other Rosa.
The Lady Bird Johnson Wildflower Center lists Yucca glauca as providing nesting materials and structure for native bees, and food and nesting for small mammals, birds, and reptiles.
The Lady Bird Johnson Wildflower Center documents the species as providing nesting materials/structure for native bees; NC State Extension likewise notes native bees use this plant for nesting materials.
Native bees nest in the dead, hollow or pithy stems of roses; leaving some cut canes standing can provide nesting habitat, as it does for other Rosa, though the tie is plausible rather than documented for this group.
NC State explicitly notes "Dead stems are used by stem-nesting bees" and recommends cutting back to 12-24 inches in late fall to let the standing stems shelter overwintering bees.
