Eastern Rock Grayling
Full scientific name:
Hipparchia syriaca (Staudinger, 1871)
Flight Period and Life Cycle
1 brood per year. Overwinters as caterpillar.
Distribution in Croatia
The distribution map is questionable. It seems the species is more common in the southern coastal area. Check the included map.
External Morphology Characteristics
The butterfly is very similar to Hipparchia fagi. They overlap in the area of Dalmatia. Examination of the male genitalia is the reference method for separating two species. The upper side of the wings is brown with bright markings and a dark spot in apex. The comparison of the underside of the wings of Hipparchia semele, Hipparchia statilinus and Hipparchia fagi/syriaca complex is here.
When lands, it keeps wings closed.
Caterpillar Host Plants
Rocky terrains with bushes and grass. Elevations: 0-1400m.
