Tenodera aridifolia
The largest mantis on mainland Japan, in green and brown forms, with a yellow spot at the base of the forelegs and purplish-brown hind wings. Oothecae laid in autumn hatch all at once in spring, releasing around 200 nymphs. Oothecae and nymphs are traded seasonally and it is a classic subject for nature study.
The Japanese giant mantis (Tenodera aridifolia) ranges over Honshu, Shikoku and Kyushu south to Tanegashima and Yakushima and is the largest mantis on mainland Japan. Some authorities regard it as conspecific with the continental Tenodera sinensis, and the 2020 Catalogue of Japanese Insects follows that treatment. Green and brown forms occur; males measure 70-90mm and females 80-95mm, growing larger southward. It is told from the similar narrow-winged mantis by the yellow spot at the base of the forelegs and the purplish-brown hind wings. Common in sunny grassland and riverbeds, it ambushes prey by day, taking insects and even small vertebrates such as frogs. Adults are active from August to October; in autumn the female attaches several oothecae of about 200 eggs to grass stems or twigs, and the eggs overwinter. Hatching falls around March in Kyushu and April in Kanto, and because the mass-hatched nymphs eat each other, keepers reduce them to a few and house them separately. Keep at 20-25C, mist for drinking water and feed live prey about every other day. Oothecae and nymphs are traded in spring, and the species is a classic subject for nature study.

Live insects (crickets, grasshoppers, butterflies; fruit flies and aphids for nymphs)
Active at 20-25C; avoid conditions above 30C. Place in a bright spot out of direct sun and air-conditioner draughts, and mist every few days so it can lick droplets, since dryness causes moulting failures.
Mates in autumn, and the female lays several oothecae of about 200 eggs. Store oothecae outdoors or in a cold room; a warm room makes them hatch in winter. 100-300 nymphs emerge together in April-May. Introduce the male while the female is eating and separate them afterwards.
Carnivorous and cannibalistic, so house one per container. Keep only as many hatchlings as can be cared for and release the rest where the ootheca was collected.
One generation a year, overwintering as eggs. Nymphs moult several times and mature in summer; adults are active August-October and captive females live to late December. In the wild only two or three per ootheca reach adulthood.
Emergence needs a case about 20cm tall with perches; without footing the moult fails. Watch for horsehair worms and for dermestid beetles and parasitic wasps on oothecae. It ignores motionless food but takes prey moved with forceps.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Japanese Giant Mantis is 20〜25℃. Avoid sudden temperature changes and maintain a stable environment.
Japanese Giant Mantis typically reaches Males 70-90mm, females 80-95mm as an adult. Size may vary depending on care conditions and individual genetics.
Japanese Giant Mantis feeds on: Live insects (crickets, grasshoppers, butterflies; fruit flies and aphids for nymphs). Aim for a balanced diet with appropriate feeding frequency.
