First Nearctic Record of Hydrellia albilabris (Meigen) (Diptera: Ephydridae), a Leafminer of Duckweed (Araceae: Lemnoideae), with Comments on Related Species

Hydrellia albilabris (Meigen) (Diptera: Ephydridae) is recorded in the Nearctic Region for the first time. Its biology and immature stages are documented, and other miners in duckweeds (Araceae: Lemnoideae) are discussed. One new combination is proposed: Hydrellia jinpingensis (Zhang, Yang, and Hayashi) is transferred from Cavatorella.
