Within a small aggregation of male digger wasps, Eucerceris flavocincta, each individual was seen posturing on perches in low vegetation and stones with wings lifted and spread apart. They challenged any approaching insect, particularly conspecific males, which were chased away or both males performed a mutual frontal display with heads almost in contact. After each aerial chase they went back to the same perch, another perch in the same area, or left.
