Comprehensive DescriptionRead full entry
Nests have been found in the ground, inside tunnels of abandoned nests of Anthophora occidentalis Cresson (Apidae) (Johnson, 1904), inside burrows made by coleopterans within old, dead flower stalks of Hesperoyucca whipplei (Agavaceae) (Hicks, 1929b) or in trap nests (Parker, 1987). According to Hicks (1929b), females collected trichomes from Lepidospartum squamatum (Asteraceae) and males seemed to have a territorial behavior similar to that reported for other species of Anthidium (e.g., A. banningense, A. manicatum). In addition to the associated organisms reported by these three authors (Table 2), Hurd (1979) also listed Nemognatha scutellaris LeConte (Coleopera: Meloidae) and Sphaeropthalma unicolor (Cress.) (Hymenoptera: Mutillidae) as parasites of A. illustre.
