From yesterday's trip: Thymelicus sylvestris feeding on yarrow.
I must admit that members of this genus, minus T. acteon, oftentimes are hard to tell apart. They tend to be of equal size and share the same color scheme, so experienced observers usually will tell you to look out for the undersides of the tips of the antennae. Since last year I've come across plenty of individuals where even that led to a genus-only entry in my notes. Latest research hints at a low possibility of T. sylvestris being a so-called "cryptic species":
