Host plants:
The larva feeds mostly on Thymus species. Eggs are usually deposited on flower buds. In the Mediterranean, also other Lamiaceae species are used.

Habitat:
Scolitantides baton settles in Central Europe especially warm grasslands with varying, mostly sparse vegetation cover. In the western Mediterranean, Scolitantides baton is quite common in the maquis and open forests with Thymus vulgaris and other Lamiaceae.

Life cycle:
Scolitantides baton forms in Central Europe usually only a single generation, more rarely also a partial second generation. The adults fly mostly in June, but also sooner or later (May to August). The caterpillar overwinters. In the Mediterranean, several generations from April to September are observed. But most adults occur in April and May.

Endangerment: threatened with extinction

Endangerment factors:
Scolitantides baton is threatened north of the Alps by qualitative and quantitative decline in grasslands (abandonment of extensive grazing, succession, overbuilding, nutrient accumulation) and the reduction of thyme, which is usually depenent on rupicolous, gappy structures and does not tolerate dense grassing. In the south, Scolitantides baton is much less endangered and locally common.

Remarks:
Scolitantides baton varies greatly in abundance and may also rarely occur more common, such as in 2004 in the Donaumoos near Leipheim (southwest Bavaria), where several dozen butterflies were observed simultaneously.

Scolitantides baton is distributed from the Iberian Peninsula across France and Central Europe and is also found in Italy. In eastern and Southeastern Europe, Scolitantides baton is replaced by the taxon vicrama.
