Genus: Ochreriades Mavromoustakis 1956
Common name: none
Ochreriades have a distinctly elongated body form and long proboscis that almost reaches the first tergum. They have an overall black coloration with yellow or ivory maculations on their thorax and abdomen, and range in length from 7–10 mm (Michener 2007).
(from Michener 2007 unless otherwise stated)
The presence of distinct yellow or ivory maculations throughout the body of Ochreriades is unique among bees in the Osmiini, and makes this genus difficult to confuse with other bees in this tribe (Michener 2007).
There are no known invasives.
Ochreriades fasciatus specializes on Lamiaceae and seems to prefer Ballota and Moluccella (Rozen et al. 2015). Females gather pollen by tapping their abdominal scopae directly on the flower anthers. Nectar from other plants may be used occasionally. The floral resources used by O. rozeni are unknown, but it is also suspected to be a specialist due to its elongated proboscis (Rozen et al. 2015).
Ochreriades fasciatus is solitary but may have aggregated nesting sites (Rozen et al. 2015). Nests are made inside preexisting holes made by other insects like wood-boring beetles in dead hardwood trees such as cypress (Cupressus sempervirens) (Rozen et al. 2015). Cells are arranged in a linear series and are partitioned by mud probably made with nectar. Larval provisions are laid out in the rear of each cell and are semi-liquid. After females have completed the nest, the entrance is plugged with pebbles and mud (Rozen et al. 2015). The nesting behavior of O. rozeni is unknown.
Ochreriades fasciatus is found in the Middle East around Israel, Jordan, and Syria. Ochreriades rozeni is found in Namibia (Michener 2007).
