Oecanthus longicauda
At night it peers through holes in leaves and trills continuously. It flies well and quickly escapes from uncovered containers.
Oecanthus longicauda Matsumura, 1904 is a tree cricket (Oecanthidae) of the Russian Far East and Siberia, Japan (Hokkaido, Honshu, Shikoku, Kyushu), Korea and China. The name appears in Meiji-era texts, and the kanji for Handan are a phonetic borrowing. It is 11-20mm long, about the size of the bell cricket, slender and pale yellow with long antennae, and adults usually have a black underside to the abdomen. Japan's five Oecanthus species are much alike, but only this one has the black abdominal underside, a useful clue though some individuals lack it. It favours humid, dense stands of kudzu, mugwort and pampas grass and is common on riverbanks. Adults occur from August to November; males sing a continuous trill at night with the head poking through a hole or notch in a leaf. Song can be heard for about two months from late summer to late autumn, but individual adults are short-lived. It is an omnivore leaning to meat, fond of aphids, and also eats mugwort and kudzu leaves. From mid-September it lays in the living stems of mugwort and similar plants, and eggs hatch the next mid-June. It is the official insect of Asahikawa. In Japan live insects are sold in autumn by singing-insect specialists.

Omnivorous (aphids and other small insects, mugwort and kudzu leaves; nymphs also pollen and petals)
Keep males in separate containers. Within a dozen or so centimetres of each other, or in the same container, they stop singing and fight. They sing best with some air movement rather than in still air.
An omnivore leaning to meat, it loves aphids, also eats mugwort and kudzu, and nymphs like pollen and petals. Captives do fine on fish food or dog food, better with a little honey mixed in. Without enough sugar and animal food nymphs stop growing and many die.
From mid-September females bite into living stems of mugwort and similar plants 5-8mm across and insert a few eggs at a time. Eggs hatch the next mid-June, so provide live mugwort plants for laying.
Adults occur from August to November and song lasts about two months from late summer to late autumn, but each adult lives only a short time.
It flies unusually well for a cricket and escapes at once from uncovered containers. Among Japan's five Oecanthus species only this one has a black abdominal underside (some lack it), a useful check when buying.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
Kantan tree cricket typically reaches 11-20mm long as an adult. Size may vary depending on care conditions and individual genetics.
Kantan tree cricket feeds on: Omnivorous (aphids and other small insects, mugwort and kudzu leaves; nymphs also pollen and petals). Aim for a balanced diet with appropriate feeding frequency.
