This seemed like a good time to check out the half-fenced flower garden to see what tracks were inside. Most of the garden was void of deer sign though the rabbit has complete freedom to go where it chooses. At the far end, away from the house, there were a few deer tracks. Deer had entered through the opening in the stone wall, wandered around a bit and exited between the railings of the unfinished fence. This fence just might work.
Their paper mache-like egg cases were side by side on a rhododendron bush. They both seem to still be intact. The baby mantis will be welcome in my garden.
