This is another native species in the USA and can be found in South Eastern of US. Unlike other
species of praying mantis, the adult female of this species has no wing. However, adult male has
full grown wings and capable to fly very well. Adult female prefer to lay ootheca near bottom part of
tree trunk. Male has a much shorter life span compared to female. Hatchling of this species is
very small and skinny. They usually emerged during early spring and became adult before winter.
Ootheca hatches in around 3 weeks. They only feed on small insects between L1-L4 stage.  Male
has a much longer antenna compared to female and this can be distinguish 2 molts before
adulthood. This species has a pair of small raptorial arms but they are able to handle large prey.
Their body shape blend well with grasses on the ground.

I started this species in 2005 with wild caught female from the park. Female are usually found
near tree trunk while males are usually caught while flying around on the field full of the tall grass.
I raised the hatchling with small fruit flies, they seem to be handling it quite well even though it
appear impossible. After L4, they can handle house fly. Hot and dry condition is alright with them,
but it is recommended to spray them once a while. Casualty for male is common during mating,
but female only need a mate to produce many fertile oothecae.
