Meet the sharp-looking bee with yellow spots and a love of soft leaves! The Wool Carder Bee collects “plant wool” to line cosy nest rooms, and the big males guard flower patches like tiny bouncers.

🧶 Plant-wool nest builder

Females don’t cut leaves like leafcutters — they scrape silky hairs from plants such as lamb’s-ear (Stachys byzantina) and roll the fluff under their body back to a ready-made hole.

• Lines a small cavity (stem, wood hole, bee hotel) with soft plant hairs,
• Adds a pollen-and-nectar “packed lunch”, lays one egg, seals the cell,
• Makes several cells in a neat row, then plugs the nest entrance.

👀 Where & when to spot them

• Season: mainly late May to early August (peak June–July).
• Places: gardens, flowerbeds, parks and sunny borders.
• Look for: yellow side-spots on a black body; females carrying fluffy “wool”; nests in small holes above ground.

🐣 Life cycle

• Late spring: Adults appear and nesting begins.
• Summer: Several soft, wool-lined cells are made and stocked with food + one egg each.
• Autumn–winter: Young develop safely inside the nest and rest over winter.
• Next year: Adults emerge to start the cycle again.

🌸 Why it matters

Wool carders are excellent garden pollinators. They visit many flowers (especially blue, tubular blooms) and help fruit, veg and ornamentals set seed.

• Males patrol flower patches to keep them busy with visitors (and mates!).
• They’re part of the Megachilidae family — the “builders” of the bee world.

⚠️ Gentle… but feisty males

Females are non-aggressive and focused on nest building. Males can be territorial — they zoom around “shoulder-barging” other insects away from their favourite flowers. Males don’t sting.

• Their guarding makes great people-watching on a sunny day!

🌍 How you can help

• Plant lamb’s-ear (Stachys) or other soft, woolly-leaved plants; add mint family plants too.
• Provide nest spots: bee hotels or drilled logs with small clean holes.
• Avoid pesticides; keep flowers blooming through summer.

Quick facts: Wool Carder Bee (Anthidium manicatum) • males often larger than females • widespread in southern Britain; seen May–Aug.
