The red-necked longhorn beetle Aromia bungii and its reproductive behaviours. a A pair in copula, where the male mounts the female’s back. b Eggs laid on the bark of the flowering cherry Cerasus × yedoensis ‘Somei-yoshino’ branch (under laboratory condition). c Eggs of A. bungii can be easily detected using UV and blue light because of the fluorescence generated after exposure. The fluorescence image was acquired using a stereomicroscope equipped with a GFP filter cube (excitation filter: 470 ± 20 nm, emission filter: 525 ± 25 nm). (Online version in colour.)

Each block represents a unique combination of fungal species (indicated by colors) and substrate tree species (indicated by shapes), arranged randomly with 1.5-m spacing between adjacent blocks. Plots (6 × 6 m) were fenced to exclude mammals, and six plots were established along an east-facing slope at 20 m intervals. Tree species: Fc, Fagus crenata; Qc, Quercus crispula; Zs, Zelkova serrata; Cj, Cryptomeria japonica (mixed 7:3 with F. crenata). Fungal species: Ba, Bjerkandera adusta; Se, Sarcomyxa edulis; Pt, Phlebia tremellosa; Tv, Trametes versicolor.
