Mediterranean mantis

Iris oratoria

"Iris oratoria" is a widespread species of praying mantis native to Europe. It is found as an introduced species in the Middle East, Western Asia and the United States. "Iris oratoria" invaded southern California in the 1930s and seems to be spreading.

"I. oratoria" is very pale when young but matures to grass green, and grows to about 6.5 cm long. The species may be distinguished from "Mantis religiosa" and other mantids with which it shares a range and general size and shape by the red-orange spot on the ventral side of the fourth abdominal segment; also, its cerci are shorter than those of "M. religiosa". The species is distinctive in having two large startling violet-brown eyespots on its hind wings which are revealed when its wings are unfolded. The adult is more slender than "Tenodera sinensis", more like "Mantis religiosa" in shape. Females have wings shorter than the abdomen, very similar to some "Stagmomantis" species, but easily distinguished if the hindwings are visible.

The Mediterranean mantis is known for two distinctive behaviours, apart from the ambush hunting common to other mantids: cannibalism and deimatic or threat displays. The sexual cannibalism of mantids known in popular culture occurs in roughly one quarter of all intersexual encounters of "I. oratoria."

When the mantis is under attack, it sets in motion a complex series of actions which combine to form a startling deimatic display. The mantis turns to face the aggressor, rears up by arching its back, curls its abdomen upwards, raises and waves its forelimbs, raises its wings to displays the large brightly coloured eyespots on the hindwings, and stridulates by scraping the edge of its hindwings against its tegmina, the leathery front wings.

Two novel "I. oratoria" survival strategies may have contributed to the expansion of this species beyond its original range, and its success in areas formerly occupied by other mantids such as "Stagmomantis carolina." Firstly, this species is capable of parthenogenic reproduction when males are scarce. Secondly, additional " I. oratoria" nymphs may emerge from their oothecae in the second season after the egg case is produced, i.e., when their siblings are already grown and are producing their own offspring.At a field site in Davis, CA, S. limbata hatched earlier in the season than "Iris oratoria", and "Iris oratoria" tended to persist longer into the year.

Compared to "Stagmomantis limbata", "Iris oratoria" eats a lesser portion of Orthopteran insects and does not eat as much long bodied insects. S. limbata adults have longer pronota and forelegs than I. oratoria adults. This difference in body size might be an important cause of the dietary differences between the species. Furthermore, the earlier hatch date for "S. limbata" also might reduce the overlap in "Iris oratoria" and "Stagmomantis limbata" diets.
