The Red Admiral has a very erratic, rapid flight. Males perch, on ridgetops if available, in the afternoon to wait for females, who lay eggs singly on the tops of host plant leaves. They prefer sap flows on trees, fermenting fruit, and bird droppings; visiting flowers only when these are not available.
