Mantis vs Mantis:
I often like to compare the “heavy-weights” of the mantis world by analyzing their ability to tackle different prey species of varying size, strength, and defenses.  I’ve already had the pleasure of working with several genera of what I consider mantid “heavy-weights”.
Sphodropoda mjobergi vs Tenodera sinensis:
I’ve raised countless of Chinese mantids, Tenodera ardifolia sinensis, which typically reach 3 inches in length (though larger, it seems in southern states of the US).  Though individuals of this species reach decent size (length-wise), their forelegs are proportionately small and weak compared to most species of other genera such asSphodromantis, Sphodropoda, Hierodula,Rhomdodera, and Tamolanica.  I have attempted feeding American mud-dauber wasps to adult female Tenodera, only to fail each time.  So far, Sphodropoda seems to have the tenacity-superiority over Tenodera.
Sphodropoda mjobergi vs Sphodromantis lineola:
In comparing the strength and aggression of the large Australian mantid with Africa’s Sphodromantis lineola (commonly known as African Giant Mantis), the degree of difficulty in tackling the Australian mud-dauber wasp was similar to, however slightly higher (from my best memory) than the African mantid’s difficulty in taking down an American mud-dauber, in other words, the African mantis seemed to have a more effective strike and grip.  The large head & forelegs of S. lineola seem to make the difference.  I also vaguely recall several occasions whereS. lineola being able to take mud-daubers with only one strike, not allowing the wasp to get even one effective sting in contrast to Sphodropoda mjobergi and Tenodera ardifolia sinensis.
