Eclectic Perambulations in the Noosphere
White-spotted sable moths are often found visiting flowers in open field, roadsides, and disturbed areas, else they are very adept at hiding underneath the leave of various plants. Larvae feed primarily on Goldenrod (Solidago).
Range: northern North America; Newfoundland to Northwest Territories, south in the west to Colorado and California, south in the east to North Carolina. Also throughout Eurasia.
3D Mathematical Beadwork by Kazunori Horibe
"Looking closely at one example, you can see how the surface curvature depends on the structure. Generally, six-sided cycles correspond to an infinite tessellation of hexagons, which makes a flat plane or can be rolled into a cylinder. But in the places where positive curvature (a spherical region) is desired, some pentagons are used instead of hexagons. And in places where negative curvature (a saddle-shaped region) is desired, some heptagons are used instead of hexagons. With this knowledge, the bead designer can control the surface outcome."
