Urocerus japonicus, commonly known as the Japanese horntail, is a species of sawfly, native to southeastern Asia. Studies show that the dispersal distance of the female is higher than the male.[2] The fungal species Amylostereum laevigatum had its first appearance in Japan via this sawfly.[3]
Ecology
This horntail lays its eggs in the trunk or branches of the Japanese cedar (Cryptomeria japonica) and the larvae feed on the sapwood. When ovipositing, the horntail introduces a symbiont fungus which either provides essential nutrients for the larvae, or which produces enzymes which help decompose the lignin or cellulose in the wood. The staining produced by the fungus reduces the commercial value of the timber.[4]
