''Japananus hyalinus'', the Japanese Maple Leafhopper, is a species of leafhoppers of the subfamily Deltocephalinae, tribus Opsiini〔 (formerly placed in tribus Scaphytopiini). Believed to be native to eastern Asia, it has been carried with the trade in cultivated maples and is now widely found in Europe, North America and Australia.〔〔 ==Description== Female 5.5mm long (even 6.5mm〔), male 4.25mm. Head comes to an acute point, head and prothorax greenish yellow. Forewings translucent with reddish veins (paler in male). In the resting position three narrow beaded bands of purplish-brown colour run more or less straight across the wings, incorporating some portions of the veins.〔 Scutellum yellow with dark markings resembling the "frowny" emoticon ☹. The eggs are inserted into the nodes of young branches, making them very difficult to detect in dormant planting stock. There is normally one generation per year (two in Italy), with the eggs over-wintering.〔 The nymphs are sharply pointed at both head and tail and are frequently yellowish.
