Differential expression of transcription factors in day 1 pupae. Transcription factors are color-coded for their pattern of differential expression—a, in red, indicates factors that are highly expressed in the proximal forewing and expressed in a falling gradient in the medial and distal forewing; b, in blue, indicates factors that are highly expressed in the distal forewing; c, in orange, indicates factors that are highly expressed in the hindwing relative to the forewing; d, in green, indicates factors that are highly expressed in the medial forewing; and e, in purple, indicates factors that are highly expressed in the proximal forewing but low in the rest of the forewing. Gray indicates no detectible expression. f lists factors with expression patterns shared between two species, and g lists factors with different expression patterns in all three species. Asterisks indicate genes which are significantly differentially expressed; all depicted genes are differentially expressed in at least one species
