Leafmining in early instars is newly reported for three species of tortricid moths in the eastern USA. Argyrotaenia amatana (Dyar) was reared from leaftying larvae found in association with recently vacated mines on Chiococca alba (L.) Hitchc. (Rubiaceae) in Florida. Aterpia approximana (Heinrich) was reared from a larva mining in Samolus parviflorus Raf. (Primulaceae) in North Carolina, a new host and distribution record, and larvae were found in New England in similar mines on Lysimachia ciliata L., a known host for this moth. Olethreutes osmundana (Fernald) was reared from larvae mining in Osmunda spectabilis Willd. (Osmundaceae) in North Carolina. For each species we summarize previous host, distribution, and phenological records. We also briefly describe the larvae and provide the first published photographs of them.
