Mine are all the imported african ones, aggression toward fingers seems to vary according to the individual mantis. I wish I had some native ones to at least breed and release into my garden, and to see if finger aggression is the same (for science).
I do know that the african ones do consume our native ones, and they can also reproduce without needing sperm which is a big advantage over our natives. The female african ones can have babies that have the exact same DNA as their mother which is a phenomenon known as parthenogenesis.
The male wetas do have the gear for a good finger chomping! They like to kick too. Havent been bitten by a male but have been kicked by a female. The huhu beetles will attempt some biting as well.
