Phylogenetic relationships between caspase sequences found in Lepidoptera in relation with their Drosophila counterparts. Amino acid alignments of caspase sequences without their prodomain were used to build a phylogenetic tree using a Bayesian inferred method with the C. elegans caspase Ced3 as an outgroup. Lepidopteran caspase clades were determined by branching patterns and are represented by brackets on the right. Posterior probabilities are shown only for nodes below 0.9. dN/dS ratio (ω) for each clade is mentioned below the clade name, except for Lep-Caspase-5 for which the number of sequences was too low to determine it.
