(Brunneria Borealis) A very slender mantis, looking more like a walking stick, similar to the grass-like mantis, both which can be found in the southern United States. The Brunner’s mantis are green, pink, and winged at maturity, and recognized by their saw blade-like thorax, and thick antennae. They were first described by Scudder in 1896. This rare, but yet common insect, can grow up to 7 inches long.Females are parthenogenetic, this means the female can breed successfully and no male is needed to fertilize the oothecae.
Egg cases can be recognized by the point at one end. Her case will contain at least 15 nymphs. Nymphs hatch from the oothecae over a period of time, rather than all-at-once, 2 or 3 nymphs at a time within several weeks, or even months, all from the same exit, the elongated point. It is said that this species of mantis, males are not know to exist. Therefore, all nymphs will only be female.

I believe I found a brown Borealis, maybe 2 inches long, here in northern Indiana. It was having trouble flying and when I tried to touch it, it actually went rigid and tried to form a stick like form (maybe a defense mechanism). Fascinating.
