Nutrition:
Parts of plants and small insects.
Habitat:
Yersinella raymondii inhabits higher growing, warm and dry, bushy grasslands, scrub, edges, open woodland, quarries, hedges, blackberry thickets and brownfields.
Life cycle:
Adults are most likely encountered in late summer and early autumn.
Endangerment factors:
At the northern limit of distribution, such as in Ticino, Yersinella raymondii is endangered by the reduction of suitable habitats due to overbuilding, reforestation, bush encroachment and agricultural intensification.
Remarks:
Yersinella raymondii is distributed in S- and SE-Europe (S-France, Italy, Balkans) and extends north to the southern Alps (e.g. Ticino).
