pannier expression foreshadowing the adult colour pattern switches red/black pigmentation processes. a The adult phenotypes of RNAi treatments targeting GFP (negative controls, GFP RNAi) and pannier (pnr RNAi) in H. axyridis (hC, hSp, hA, h) and C. septempunctata. Scores in the lower left corners indicate penetrance of the loss-of-pattern phenotype in surviving animals. b The pattern of pannier expression (pnr) in the dorsal elytral epidermal cells immediately before or after pigmentation (76−84 h AP). Left panels indicate the corresponding adult elytral phenotypes (hC and h) adapted from Fig. 2a. White arrowhead, the region with a weak signal. Black arrowheads, the regions with intense signals. Scale bars, 1 mm
