Remarks
"Thrypticus occurs in all realms and is well represented in the New World. The Nearctic fauna is comprised of small species occurring on herbaceous vegetation on stream banks and margins. Larval stages of Thrypticus are phytophagous and feed as miners of Cyperaceae, Poaceae, Juncaceae, and Pontederiaceae."(1)
Species identification normally requires close examination of male genitalia.
