I haven't noticed any caterpillars this year, but that adults are in

Are you sure these are Cinnabars? I could be wrong, but I think the
highly similar Burnet Moth feeds on vetch.

I suspect that you're right. (Three species of Zygaena have epithets
referring to vetchs, birds foot trefoils and clovers, respectively -
tho' this need not be a reliable guide to food plant.)
