The Yellow-banded Skipper (Pyrgus sidae) is a species of skipper (family Hesperiidae). It is found in southern and eastern Europe.
Pyrgus species are usually difficult to separate in the field but P. sidae is a notable exception. It is the largest member of the genus found in Europe with a wingspan of 32–38 mm and can be instantly recognized by two bold black-edged yellow bands on the underside of the hindwings. The dark brown upper forewings are also boldly marked with numerous large white spots. The adults fly in June and July.
The larval food plant is Abutilon avicennae.
