What specific feature identifies the male Anthidium manicatum abdomen tip?
Answer
Three prominent, pointed projections
The male *Anthidium manicatum* is readily distinguishable by the posterior end of its abdomen, which features three conspicuous, stiff, and pointed projections, often described as spines. These structures contrast sharply with the female's abdominal termination. The presence of these three spines, combined with distinct large pale yellow spots on the sides of the last few abdominal segments, gives the male a noticeably armed appearance designed partly for territorial defense and display against rivals. The female, conversely, possesses a smooth, rounded tip lacking these defensive projections.
