Not particularly unusual in
form, but the cerambycids of the genus Sphingnotus (tribe Tmesisternini) must surely be among the most beautiful in the world -
Sphingnotus mirabilis -

I saw my first Rosalia alpina in the Jura mountains (France) when I was a kid (about 10 years old). I was so impressed, I still perfectly remember that wonderful sight today !

Yes, a striking species for sure! Interestingly, the only species of this genus in North America, Rosalia funebris, Motschulsky, 1845, the Banded Alder Borer, is known to be attracted to fresh paint and both sexes can be fairly numerous on freshly painted buildings etc. It's thought that certain volatiles in the paint must mimic a pheromone used by both sexes, rather than mimicking a host plant volatile due to the lack of other species attracted.

Other beetles are attracted to construction materials. Metallic wood borers were always landing on the roof during the season, so do water
beetles, seeing the bare wood apparently. I always saw the interaction as a visual attraction.
