The adults feed on nectar from available flowers, and sometimes sap seepage from trees. Normally the last of the season's brood survive as larvae until the next season, but in some areas it survives as a dormant adult over winter.
In this context, adults obtain nourishment by sipping nectar from flowers and gathering sap that trickles down trees. Typically, only the last remnants of the season's young survive as larvae until the following year, but in some regions, they persist as a resting adult during the winter.
