Insecta phylogenetic timetree used in this work. Red branches represent six independently-evolved hematophagous lineages. Rhodnius prolixus and Cimex lectularius represent two independent events of hematophagous evolution, the non-hematophagous genomes of their sister groups were not available. Diptera (blue box) and Hemiptera (green box) are the groups with multiple hematophagous lineages. Green and purple squares indicate lineages with rapid expansions in multiple hematophagous lineages, while blue and brown squares indicate lineages with rapid contractions in multiple hematophagous lineages
