What distinctive physical feature helps identify the male Wool Carder Bee?
Answer
Prominent mandibles
The recognition of the Wool Carder Bee often relies on specific morphological cues, particularly when differentiating between the sexes. Males of *Anthidium manicatum* possess a very noticeable and distinctive physical characteristic: prominent mandibles. These specialized mouthparts are utilized in their territorial behavior, specifically in engaging in defense against rival males who encroach upon areas where females are active or near high-value flower resources. While both sexes share a generally fuzzy appearance, the presence of these exaggerated mandibles is the key feature used to identify the male.
