Isophrictis similiella
Isophrictis similiella is a small gelechiid moth described by V.T. Chambers in 1872. It is known from scattered localities across central and eastern North America. The species has a wingspan of approximately 11 mm. Larvae are documented to bore into the receptacles of Solanum carolinense (Carolina horsenettle) and the flowerheads of Rudbeckia hirta (black-eyed Susan).
Synanthedonini
clearwing moths
Synanthedonini is a tribe of clearwing moths within the family Sesiidae, characterized by wasp-mimicking appearance and larval boring habits in plant tissues. Members exhibit diverse host plant associations across multiple families including Lauraceae, Fagaceae, Rosaceae, Fabaceae, and Proteaceae. The tribe has been documented across North America, Central and South America, Taiwan, and other regions, with several species recognized as economically significant pests of ornamental and native plants. Molecular studies using COI barcoding support species-level identification but reveal phylogenetic complexities, including the atypical placement of some genera previously separated based on morphology.
