description Ptilothrix bombiformis Overview
Ptilothrix bombiformis, commonly known as the hibiscus bee, is a solitary bee species native to North America. It exhibits Batesian mimicry by closely resembling a bumblebee in size and coloration, which provides protection from predators. The species is oligolectic, meaning it forages specifically for pollen from plants in the mallow family, particularly hibiscus flowers. Females are ground-nesters, excavating tunnels in hard-packed soils to lay their eggs and provision them with the collected pollen.
help Ptilothrix bombiformis FAQ
Why is Ptilothrix bombiformis called the hibiscus bee?
Ptilothrix bombiformis is commonly called the hibiscus bee because it is closely associated with hibiscus flowers. Its specialized pollen-gathering behavior makes hibiscus and related plants important food sources.
Does Ptilothrix bombiformis look like a bumblebee?
Yes, it resembles a bumblebee in size and coloration. This is an example of Batesian mimicry, in which a relatively less-defended species gains protection by resembling a better-defended one.
What does oligolectic mean for this bee?
Oligolectic means that Ptilothrix bombiformis collects pollen from a narrow range of related plants rather than from almost any flower. In this case, hibiscus is central to its documented floral association.
Is Ptilothrix bombiformis a social bee?
No, it is a solitary bee native to North America. Individual females construct and provision their own nests rather than living in a large cooperative colony.
