A preliminary molecular phylogenetic study of Limacodidae, slug moths, was undertaken. From the LepAToL tissue collection, 30 representatives of 10 of 11 proposed generic groups and 4 outgroups were borrowed for this project. Standard DNA extractions were prepared for all representatives. The project design involves sequencing 1 mitochondrial gene (COI, 1500 bp) and 2 nuclear genes (Ef1-a, 1200 bp; portion of CAD, ~1200 bp). To date, partial sequences of COI and Ef1-a) have been obtained and aligned. Both maximum likelihood and Bayesian analyses were performed. These preliminary phylogenetic results are discussed and as well as implications for the evolution of larval body types (smooth versus spiny/hairy).
