Overview

Anthidium (Anthidium) parkeri are black with brown tarsi and yellow maculations (Gonzalez and Griswold 2013). Females have white pubescence except for some brown hairs on the clypeus, supraclypeal area, frons, vertex, inner basitarsi, T1T4 discs, and center of S6. Females have a body length of 10.0–12.3 mm, and males range in length from 11.5–16.9 mm (Gonzalez and Griswold 2013).

Diagnostic characteristics

(modified from Gonzalez and Griswold 2013)

May be confused with

Anthidium parkeri may be confused with A. maculosum due to the presence of anterior hind tibial carinae and dull frons with coarse and sparse punctures. Female A. parkeri can be differentiated from A. maculosum by the absence of dense tomentum on the outer surface of the basitarsi, dull clypeus, and shiny scutum and scutellum with coarse, sparse punctures. Male A. parkeri can be differentiated from A. maculosum by a small medial denticle on the apical margin of the clypeus, apically subtruncate median lobe of S6, and shape of S7 and S8 (Gonzalez and Griswold 2013).

Phenology

Anthidium parkeri adults have been recorded in flight in March, and from late June to December (Gonzalez and Griswold 2013).

Host associations

Anthidium parkeri has been observed visiting Vitex pyramidata (Lamiaceae) and Cuphea paucipetala (Lythraceae) (Gonzalez and Griswold 2013).

Nesting behavior

Nesting behavior is unknown.

Distribution

Anthidium parkeri are native to Mexico and northern Guatemala. In Mexico, they are found in Sinaloa and from Durango to Chiapas. They primarily occur in dry and pine-oak forests (Gonzalez and Griswold 2013). None are known to occur in the U.S. or Canada.
