Hebard conducted the last known analysis of Litaneutria in 1935.  He studied samples of Litaneutria specimens that were collected from several different locations within the central and western United States and concluded that all of the previously described species should be considered...

Species treatment for Yersiniops sophronicus (Rehn & Hebard, 1908) completed. This species differs from its congener in having a more elongated pronotum and dorsal surface of compound eyes greatly extended into acute points. Adult males are typically encountered from late July to early...

Yersiniops solitarius (Scudder, 1896) species treatment completed. Despite their inability to fly, adult males are attracted to lights at night.  This species is quite active and oftentimes jumps several inches to escape enemies.  They occasionally produce significant quantities of brown...

Yersiniops solitarius, female “Praying Mantises of the United States and Canada”]https://www.researchgate.net/project/Praying-Mantises-of-the-United-States-and-Canada

Species treatment for Thesprotia graminis (Scudder, 1877) completed This particular analysis revealed some interesting reproduction behavior that has not yet been seen before with other Nearctic species. Once alighted atop the female, the male may clumsily turn in circles multiple...

Tenodera sinensis is native to China and Japan.  Its propagation around the country has largely been due to human meddling... and as such, many of the native Mantodea populations have been severely affected.  Another example of this is Mantis religiosa in the mountainous west, where this...

Tenodera sinensis can show up anywhere within the continental United States, as previously explained.  The distribution map represents stable, intergenerational populations. 

Tenodera sinensis species treatment completed.  This particular species, due to its interesting large size and commercial availability, has been the subject of much reproductive and ethological experimentation over the past few decades. The cumulative results of this massive amount of data has...

This is correct.  Cross-breeding usually does not produce viable offspring.  In the few cases that two congeners successfully mate, produce fertile oothecae that bring forth healthy nymphs that can mature properly, there has been no documented evidence that I am aware of that the adults produced...

Nymphs will emerge within 6 weeks if not exposed to the cold; otherwise a 7-9 month diapause occurs over the cooler, winter months. First instar nymphs will begin taking water from droplets within the first day of their emergence.  Thereafter they begin feeding upon small prey items, including...

Nymphs will emerge within 30-110 days if not exposed to the cold; otherwise a 7-9 month diapause occurs over the cooler, winter months. “Praying Mantises of the United States and Canada” https://www.researchgate.net/project/Praying-Mantises-of-the-United-States-and-Canada

Iris oratoria, male “Praying Mantises of the United States and Canada” https://www.researchgate.net/project/Praying-Mantises-of-the-United-States-and-Canada

Not accurate regarding the stigma presence/coloration... but, yes, this is Stagmomantis carolina, female. 

Thanks for the information, Mark.  Yes, there does seem to be some sort of perceptual nexus in regard to mate finding/selection.  Pheromone signatures are certainly at play for long-distance location but visual ques seemingly take over once a potential pair are within reasonable distance of each...

Species treatment for Tenodera angustipennis Saussure, 1869 completed. The U.S. distribution of this species is confined to a significantly smaller range in comparison to its much more widespread congener, T. sinensis.  This same dynamic occurs in Japan, where T. angustipennis is found in...

Confirmed. 

Keep the ootheca outside and bring it back inside around early May.   It'll be fine. 

Species treatment for Stagmomantis limbata complete.  This species is spontaneous parthenogenetic, in that females are noted to be capable of asexually reproducing offspring that are non-viable and will die prior to reaching maturity.  An adult male has been recorded mounting (not copulating...

None of these photos are of Stagmomantis gracilipes.  Dimensions of head capsule, shape/placement of frons and clypeus, prothoracic leg morphology, and pronotal width/length would suggest Stagmomantis "californica" wheelerii. 

Species treatment for Stagmomantis gracilipes completed. This species is infrequently encountered within desert grasslands and mountain meadows of southern Arizona and represents one of the rarest mantises in the U.S. territory with one of the smallest range distributions. Nymphs resemble...
