Well it’s been almost 2 weeks with no praying mantis
evidence at all. The egg cases appear to
have all hatched, and they seem to have all run off. My girlfriend found a lone healthy-looking mantis on some cilantro plants that we have and it was kind enough to pose long enough
for me to get a few shots. Noticeably
bigger, as expected, but also much greener than the young ones we observed. There has been a noticeable reduction in the bugs in our garden, but the reasons are unclear as the garden-eating bugs seemed to have just about disappeared way before the mantises were hatched, so it is unclear at this point.
