“Shared” and “Unique” SDs among 5 species. a “Shared” and “Unique” SDs in each genome. Red represents “Unique” SDs while black represents “Shared” SDs. b SDs classification of the five species based on the existing SDs (marked as “+”) and absence SDs (marked as “-”). We classified the SDs into five groups to analyze evolutionary history of SDs in Lepidoptera genome. Group A are the potential ancestral SDs events. Group B showed the SDs that were only lost in Noctuoidea and Bombycoidea while Groups C, D and E showed regions where duplication patterns were inconsistent with the generally accepted phylogeny. Such a scenario could arise as a result of a de novo origin of SDs or as a result of deleted events, which might have played a role in lineage-specific evolution. “n” represents the number of group A, B, C, D or E. c Identity comparison between “Shared” and “Unique” SDs in the genomes of the five Lepidopteron species. The identity of “Shared” SDs is marked as black while the identity of “Unique” SDs is marked as red
