Overview

Anthidium (Anthidium) rodriguezi are black except for the dark brown coloration on their antenna and tarsi and yellow maculations. Females have white to cream pubescence with darker hairs on the clypeus, supraclypeal area, vertex, scutum discs, coxae, trochanters, inner tarsi, and S6 (Gonzalez and Griswold 2013). Females range in body length from 13.1–19.2 mm. Males have short, stout, simple, dark-brown hairs on the ventral surface of the mesepisternum, metepisternum, and base of the hind coxa. Males range in body length from 16.9–21.5 mm (Gonzalez and Griswold 2013).

Diagnostic characteristics

(modified from Gonzalez and Griswold 2013)

May be confused with

Anthidium rodriguezi can be differentiated from all Anthidium species in the U.S. except for A. chamelense by their large body size and entirely or nearly entirely black abdomen. Female A. rodriguezi can be differentiated from A. chamelense by the T6 with acutely pointed lateral and sublateral spines. Male A. rodriguezi can be distinguished by their T6 with lateral spines that are reduced or absent (Gonzalez and Griswold 2013).

Phenology

Anthidium rodriguezi adults have been recorded in flight from June to early December, with peak activity occurring from October to November (Gonzalez and Griswold 2013).

Host associations

Anthidium rodriguezi has been observed visiting Bidens sp. (Asteraceae), Salvia leptostachys, and S. melissodora (Lamiaceae) (Gonzalez and Griswold 2013).

Nesting behavior

Nesting behavior is unknown.

Distribution

Anthidium rodriguezi are found in Honduras, Guatemala, and Mexico (Gonzalez and Griswold 2013). In Mexico, they occur from Chiapas to Sinaloa, Nuevo Leon, and Tamaulipas. They are primarily found in dry forests, pine-oak forests, and moist forests (Gonzalez and Griswold 2013). None are known to occur in the U.S. or Canada.
