1. Dataset (format: csv).

This dataset shows the caterpillar (Macrolepidoptera) traits of aposematism/crypsis and group-living/solitary-living which were from the Tullberg and Hunter (1996) [1].

The dataset also include genes of CO1 and EF1a (collected from the Genbank [2] by the date 1 July 2018) for these caterpillar species.

2. Alignments (format: nex).

These are the alignments of CO1 and EF1a genes for the five superfamilies in Macrodoptera (Papilionoidea, Bombycoidea, Drepanoidea, Geometroidea, Noctuoidea). The acession numbers for CO1 and EF1a are given in the above dataset.

For each of the five superfamilies, CO1 and EF-1a nucleotide sequences are aligned using MUSCLE [3] with default settings in the software MEGA7 [4], and concatenated the aligned sequence together using the software SequenceMatrix [5].

3. Phylogenetic tree (format: nwk).

BEAST v1.10.4 [6] is used to estimate Bayesian trees separately for the five superfamilies. The generalised time reversible model (Tavaré, 1986, [7]) is used as the substitution model with gamma distributed rate variation and an estimated proportion of invariant sites (Yang, 1994, [8]); and the strict clock model [9] is used as the molecular clock model. The five maximum clade credibility superfamily trees were subsequently grafted together based on the higher-level topology and divergence times from the TimeTree database [10]-[13].
