->Population: Trend estimation by list-length analysis shows up a significant -16% long term decline of the species observation probability when visiting favourable grids within 24 years (-0,67% per year); the numbers of individuals seen by observers seem to decrease slighly over the periods (decreasing medians by period) ||
->HabInfo: Many favourable sunny rocky habitats disappear due to natural succession; some were restored by tree and bush cutting during the last two six-year cycle in the framework of Life projects, but it is not known if it compensated the loss during the same interval. ||

Information provided in the field 2.8.2: Reported additionnal information: ||
->Range: Area and short-term trend are based on species distribution models for the periods 2007-2012 and 2013-2018, based on both casual and standardised species observations.
Survey efforts since 2013 has led to a large increase in species distribution knowledge, mostly filling gaps between known populations.
Change in reported values is due to the use of a different resolution in the range tool (grids5x5 in 2013 and grids10x10 in 2019). ||
->Population: Population size: estimation based on species distribution modelling from presence data in the 2013-2018 period. Unit = grids 1x1. The maximum corresponds to the number of suitable grid cells provided by the model. The minimum is the maximum value multiplied by the naïve site occupancy during our monitoring (88/170=52%).
Short-term trend: estimation based on the 137 grids1x1 surveyed both in 2010-2012 and in 2016-2018 in the frame of a dedicated monitoring. Unit = grids1x1. The species was present in 62 grids in 2010-2012 and in 65 grids in 2016-2018 (+5%), which is considered as stable (less than 1% change per year). Based on expert's opinion, the number of individuals by population is likely increasing as well. However, the density of suitable habitats and hence the population size in terms of individuals is still considered far below the historical situation.
Change in reported values are mainly due to the use of a different unit (grids5x5 in 2013 and grids1x1 in 2019). ||
->HabInfo: Based on repeated surveys of a sample of sites, the habitat quality is considered as stable. A part of the occupied sites are however subject to natural succession, but without substantially affecting the habitat quality at the scale of the short-term trend period (2010-2018). Based on expert's opinion, important works have recently undertaken on railways allowing a recolonisation of the species. The species is well represented in the dry walls of the vinyards. Some examples of dry wall restauration projects followed by colonisation of the species have been observed. However, the density of suitable habitats is still considered far below the historical situation. ||
->Future: A growing attention is given in the protection and the restauration of dry walls. In addition, the global reduction of chemicals in vinyards and in public areas should be beneficial for the species. However, the species still requires attention in the development of infrastructures outside protected areas. ||
->Conclusion: Species which followed some decline in former years but nowadays likely to be improving thanks to conservation measures and potentially thanks to climate change. A dedicated monitoring provided more accurate data. Special care are still required in habitat management and development projects. ||
