We compared egg-laying patterns and landscape occupancy of two sympatric lycaenidae butterflies inhabiting xeric grasslands, vulnerable Polyommatus thersites and critically endangered Polyommatus [Agrodiaetus] damon, both developing on sainfoin, Onobrychis spp. Females of bivoltine P. thersites oviposit on host plant leaves at a relatively low height in both spring and summer generations. Females of univoltine P. damon oviposit to senescing inflorescences, in significantly higher heights, and the species is hence vulnerable to summer mowing or grazing. On a landscape scale, both species tended to occur at sites with diverse sward management, including temporarily unmanaged patches. Grassland management must respect the needs of the most vulnerable species, maintaining a high diversity of conditions within individual sites.
