There is also an old Russian cards game with the exact same name; mostly for children (other name is «Witch»). Where the Akulina is the nickname for the queen of spades.
The patroness of the name is the holy martyr Akilina the Elder (Aquilina). 12-year-old Aquilina lived in the 3rd century and, as a child, turned to the faith of Christ. She also tried to direct her friends on the right path, for which she was executed. In the Russian peasant consciousness, Saint Akilina was transformed into the image of Akulina the buckwheat - the patroness and accomplice of the buckwheat harvest. Her day was celebrated at the end of June (June 26, new style; 13 - old style). On the day of Akulina, bunches of this plant, plucked from the fields, were decorated with icons in houses. On Akulina-buckwheat, it was customary to cook porridge and treat them to the poor, so the holiday was also called "the Day of Mir (mundane) porridge". Since on this day blood-sucking insects (mosquitoes, horseflies), from which the cattle suffered, became active on this day, her second nickname was "Akulina - Pick up the tails" The name was popularized by A.S. Pushkin in the story "The Young Lady-Peasant" (1830).
