Anthidium (Anthidium) quetzalcoatli are black with dark brown coloration on their antennae and femurs and yellow maculations. Females have white pubescence except for some yellow to brown hairs on the vertex, scutum, axilla, scutellum, and inner tarsi (Gonzalez and Griswold 2013). Females range in body length from 10.0–12.3 mm, and males range in length from 13.1–14.6 mm (Gonzalez and Griswold 2013).
(modified from Gonzalez and Griswold 2013)
Anthidium quetzalcoatli can be differentiated from all Anthidium species in the U.S. by the carinate preoccipital ridge. Additionally, the shape of T6 in females and the shape of T7, S6, and S8 in males can be used to differentiate A. quetzalcoatli from other species (Gonzalez and Griswold 2013).
Anthidium quetzalcoatli adults have been recorded in flight from June to September (Gonzalez and Griswold 2013).
Anthidium quetzalcoatli is a specialist on Indigofera palmeri (Fabaceae) (Gonzalez and Griswold 2013).
Nesting behavior is unknown.
Anthidium quetzalcoatli are found in southern Arizona (Gonzalez and Griswold 2013). In Mexico, they occur from Oaxaca to Sonora. They are primarily found in dry forests and occasionally in pine-oak forests (Gonzalez and Griswold 2013).
