American Serpentine Leaf Miner

Liriomyza trifolii, known generally as the American serpentine leafminer or celery leafminer, is a species of leaf miner fly in the family Agromyzidae.

L. trifolii is a damaging pest, as it consumes and destroys produce and other plant products. It commonly infests greenhouses and is one of the three most-damaging leaf miners in existence today. It is found in several countries around the globe as an invasive species, but is native to the Caribbean and the Southeastern United States.
