Anthocharis gruneri Herrich-Schäffer, 1851

Host plants:
The caterpillar lives on a few tiny-flowering Brassicaceae, especially on Aethionema species.

Habitat:
Anthocharis gruneri colonizes shrub rich and dry slopes, rocky embankments, stony road sides and similar dry and warm places with open soil. The larvae are recorded at fully sun-exposed spots as well as at semi-shady ones.

Life cycle:
The pupa hibernates and the adults fly from late March to late May. The caterpillar might be expected from late April to June. I recorded eggs and young to half-grown larvae quite common alway on Aethionema at suitable places in Northern Greece (Siatista, Kozani) in 800-1000m asl in mid-May 2014. The larvae typically rest head-down in the inflorescence which is eaten from the tip.

Remarks:
Anthocharis gruneri is distributed from Albania, Macedonia, Greece and southern Bulgaria across Turkey and Israel to Iran.
