Gnorimoschema terracottella
Gnorimoschema terracottella is a small gelechiid moth described by August Busck in 1900. The species is characterized by distinctive reddish-brown forewings with complex white patterning and dark dusting. Its larvae are leaf miners on Iva imbricata, a composite plant in the southeastern United States. The species is known from only two states, Florida and Alabama, and is one of approximately 100 described species in the genus Gnorimoschema.
Ophraella notulata
Marsh Elder Leaf Beetle
Ophraella notulata is a Nearctic skeletonizing leaf beetle in the family Chrysomelidae, found in Gulf Coast states of the United States and Mexico. It was previously described as O. integra (LeConte), now synonymized with O. notulata (Fabricius). The species is specialized on host plants in the Asteraceae family, primarily Iva frutescens (marsh elder), with documented ability to utilize Ambrosia artemisiifolia (ragweed) as an alternative host. Research has demonstrated complex transgenerational effects of host plant on offspring fitness and behavior.
