Sceliphron caementarium can reach a length of 24–28 millimeters (0.94–1.10 in). Petiole is black, about half the length of the entire abdomen. The thorax shows various yellow markings, while the abdomen is normally black, with yellow propodeum (typical of females). The eyes are black, the antennae are black and the legs are yellow, with black trochanters and femurs. The wings are a tawny color. (information from Wikipedia)
I saw these 3 land near me as I was leaving work and I quickly ripped my camera from its bag and set up for macro shots. Thankfully I captured this photo of 2 males vying for breeding rights with a female.
