With over 5000 described species, Phycitinae is the largest subfamily within Pyralidae, or snout moths.
A number of collaborators are involved in studies of taxonomic, phylogenetic, and evolutionary aspects within the Phycitinae subfamily.
The most prominent of these are:
- a phylogenetic framework with focus on North American genera
- construction of a bioinformatics website for cactus-feeding phycitines and their relatives
- a study of the morphology and phylogenetic importance of Abdomen 8 modifications in male phycitines, using imaging techniques
