This sufficiently orange-flowered plant is called tansy (Tanacetum vulgare), boerenwormkruid in Dutch; it is very popular with insects, and they can find food here until fairly late in the season.
The guest star today is a holly blue (Celastrina argiolus), boomblauwtje in Dutch:
Olympus Stylus 1s, 195mm, ISO100, f5.6, 1/400s
A portrait shot from up close, note the focal length:
Olympus Stylus 1s, 42mm, ISO125, f8, 1/160s
Here it is showing a bit of the top of its wing, where the blue sits that gave it its name:
Olympus Stylus 1s, 300mm, ISO100, f5.6, 1/800s
Thanks for watching!
