Summary diagrams of wing development and gene expression patterns in Z. nevadensis and H. sjostedti determined in this study. The processes of wing formation are indicated along the course of nymphal development, followed by the wing expansion at the time of imaginal molt (top row for each species). Expression patterns of representative genes (vg and Kr-h1) are indicated: Kr-h1 is abruptly downregulated at N2L and NL, while vg is gradually upregulated at the late stage of the final-instar nymphs. Although statistically significant differences were not detected, expression peaks of most examined genes were seen at N2E in Z. nevadensis, while they were seen at NE in H. sjostedti (dotted lines)
