A Crab Spider on a lovely, rare wildflower.

Peter Baye noticed this yellow Crab Spider on a King's Gentian, Gentiana Sceptrum.

Crab Spiders can change their color to match their hiding place, at least from yellow to white. But they can't match the vivid blue of the Gentian!

Thanks to Peter for allowing me to share his photo with you here.
