Carolina mantids (Stagmomantis carolina) are the most abundant native mantids in North America. The heavy-bodied females are short-winged and unable to fly, while the males are long winged, slender and relatively good fliers.
We found large numbers of green individuals at our collecting site near the intersection of First and Windsor in Champaign, IL last Sunday. We did not encounter any gray or brown individuals. Though all three colors can be common, browns and greens are most often encountered throughout east central Illinois.
A brown individual, her egg case (ootheca) and hatching offspring can be found in my first blog entry, Mantids, mantids and more mantids.
