EdU Praying Mantises


According to comments by @Manassas , the HK IDing of Hierodula is mixed up.
"There aren't any Hierodula membranacea distributed in China. All the Hierodula membranacea in China now called H. formosana and H. chinensis. Also the lacy wings can't be the identify pointer for every mantis will get lacy wings when it get old just like age spots on human face." and "In fact many H. formosana in HK are mistaken as H. patellifera"

Large green ones:
Hierodula: Should be only H. patellifera, H. formosana, H. chinensis (maybe)

Tenodera genus: Very large, often brown but not always, with green "stripe" of an underbody under the wings. Manassas wrote "skinny and has a green strip on the frontier of its forewings. Also its pronotum extension is straight and its face is striped." https://www.inaturalist.org/observations/27253757
(Includes at least 4 possible species of giant mantises. https://www.inaturalist.org/observations?verifiable=true&taxon_id=71035&place_id=any&preferred_place_id=9853&locale=en-US&view=species&rank=species,subspecies,variety)
for Tenodera aridifolia (Japanese Giant Mantis), see https://www.inaturalist.org/observations/11216934
for one IDed at genus level only, https://www.inaturalist.org/observations/12407969

Statilia maculata: Asian Jumping Mantis; Smaller, brown, with distinctive spots/markings on front legs. e.g. https://www.inaturalist.org/observations?verifiable=true&taxon_id=358085&place_id=any&preferred_place_id=9853&locale=en-US&view=species&rank=species,subspecies,variety

Acromantis? (Genus level for Japanese Boxer Mantis; but I'm not sure I'm correct about this set): Smaller, with green under the brown wings; and relatively broad/distinctive. e.g. see https://www.inaturalist.org/observations/23860238, but see one I thought was Acromantis that was moved to H. Formosana https://www.inaturalist.org/observations/27561755 [wings are lacy/like a screen-- this can just be a sign of age? https://www.inaturalist.org/observations/16587515 ]

Tussock moths & others to keep at genus level

Webpage describing Tussock moths

Tribe Nygmiini includes the Artaxa, Euproctis, Nygmia, & Orvasca species. Great confusion in this tribe.
Artaxa (faintly marked small yellow moths): Mostly keep at genus level

Orgyia postica (Cocoa tussock moth) vs. Dasychira chekiangensis (Zhejiang Tussock moth): The lines around the "eye" pattern in the center of the wings pulls in and becomes narrow in O. postica as it reaches from the costa to the body; in D. chekiangensis it is more even / straight (if the lines are visible at all). (Thanks to @cosmophasis) (also see https://www.inaturalist.org/observations/12281403 )

Sexual dimorphism in D. chekiangensis .


Arctornis: At least 12 species in HK but you can't tell them apart by looking; keep at genus level. (see comments at https://www.inaturalist.org/observations/17744371)

Carriola ecnomoda: Sexual dimorphism. Also, all HK ones need to be changed to Carriola seminsula! (https://www.inaturalist.org/observations/23100844)

Abraxas: "there are 2 species of Abraxas currently known from HK but they cannot be identified by field observation - they need to be chopped :-( Sadly the markings are not an accurate way of identifying to species level." https://www.inaturalist.org/observations/12352632

Euteliinae: this subfamily "is called "turn-tails" - due to the peculiar manner in which the abdomen is held when the moth is at rest." https://www.inaturalist.org/observations/183867
