A fly, which is being referred to as the RICE WHORL maggot due to its similarity to an Asian fly (Hydrellia philippina), is damaging rice in Louisiana. This pest, whose identification is still under review, is potentially a new species for the United States. A taxonomist at the Smithsonian Institute suggests it could be an unnamed species from Costa Rica. In Louisiana, rice fields have been affected in Concordia, Jefferson Davis, Saint Landry, and Vermilion parishes. The fly has also been observed in some Texas rice fields, but on a smaller scale.
