Corpse flower blooming
These are the egg cases of the non-native Chinese praying mantis. Our horticulturists have found them throughout the gardens. Note that they are poofy and can b...e found on almost any plant material. These non-native praying mantises are out of balance in our ecosystem and consume our pollinators, butterflies, and native Carolina mantises in huge numbers.
Our horticulturist says, "There have been times when I have seen a pile of butterfly wings on the ground to find when I looked up a Chinese mantid poised like a sniper on a flowering perennial." Our staff's method of disposal is to smash or burn them.
EDIT: We've added a photo of the native egg case and native adult Carolina mantis for reference!
