help Anthidium maculosum FAQ
Does Anthidium maculosum live in a hive?
No. Anthidium maculosum is a solitary bee in the Megachilidae family, so each female prepares and provisions her own cavity nest rather than living in a honeybee-style colony.
What does a female Anthidium maculosum collect from fuzzy plants?
She scrapes soft plant fibers from fuzzy leaves and uses the material to line her brood cells. Lamb's-ear and mullein are familiar examples of woolly plants used by wool-carder bees. [Wool-carder bee research](https://academic.oup.com/zoolinnean/article/168/2/221/2433440)
Why are male Anthidium maculosum bees so aggressive?
Males defend flower patches where females feed and mate, so they may charge or strike other insects that enter the territory. In Anthidium, larger males can use spines at the end of the abdomen to attack intruders.
How is Anthidium maculosum different from the European wool-carder bee?
Anthidium maculosum is a North American species, while the European wool-carder bee is Anthidium manicatum. Both collect plant fibers and have territorial males, but they are separate species with different native ranges.
