LepTree.net is an international, community collaboration dedicated to advancing progress toward a phylogenetic tree for all Lepidoptera. Our interactive web tools allow all lepidopterists to exchange information and coordinate their research efforts with each other. Three specific projects are designed to increase knowledge of lepidopteran phylogeny.

LepTree is based in North America and supported by the U.S. National Science Foundation’s Assembling the Tree of Life program (read/download the full proposal). LepTree is closely coordinated with the related LepSys initiative, and the Systematics of Ditrysian Lepidoptera project (see Project Directory entry by L. Kaila), both based in Europe.

Figure 2 from Wahlberg and Wheat, 2008. Results of Bayesian analysis of the combined data set partitioned according to gene region (11 partitions). Circled numbers to the left of a node refer to nodes of interest. These were found in all analyses of the combined data set. Support values for these nodes are found in Table 2. Uncircled numbers to the left of a node are Bayesian posterior probabilities from the 11-partition Bayesian analysis. Clades are colored according to the five major lineages identified in this and previous studies (e.g.,Wahlberg et al., 2003): Blue = Libytheinae; orange = Danainae; yellow = satyrine clade; green = heliconiine clade; red = nymphaline clade. Butterflies shown are voucher specimens used in this study, from top to bottom: Libythea, Greta, Calinaga, Melanitis, Heliconius, Cyrestis, and Melitaea.
