Every year in the dog days of late summer, I get dozens of spicebush swallowtail 
butterflies congregating on the grave road where it bends at the base of my driveway. Ages ago a gravel truck put a but rut between the road and the drainage ditch. That rut retains water. The combination of the hot afternoon sun on the gravel, the fine limestone dust and the shallow water draws these guys like a magnet. I drive very slowly to let them fly away. Few folks do…
There are also brilliant fritillaries, red admirals, sulphurs, tiger swallowtails and some fast little fellas that may be skippers.
As the weather cools, this beauty will end, sigh.
