Tiny dead praying mantis

Why or how is it, that I pass back and forth, retracing my steps two dozen times, and then on the 25th trip something catches my eye. I pause. And can't believe what I see: the perfect, tiny, dead carcass of a young praying mantis curled lightly on the edge of the banister, halfway up the stairs. I suspect that I inadvertently brought it in on a bunch of Catmint clippings. Whatever clumsy, accidental part I played (if I even did), I regret. I say a silent prayer that when and if I go on unexpected journeys/ adventures, I do not meet with such disastrous consequences. I am happy to report that there are at least two still clambering around in the garden out back.
