SWD look-a-likes

For those of us picking through the burgeoning number of vinegar flies caught in our traps to find the single female or male SWD, Faruque Zaman and Dan Gilrein, Suffolk County Cornell Cooperative Extension, Long Island Horticultural Research and Extension Laboratory, have written an article published in Vol 12, No 7 of the NY Berry News, starting on page 3. Two excellent figures show male and female SWD next to look-a-likes. Another excellent resource for SWD identification is the fact sheet from Penn State, Spotted Wing Drosophila, Part 1: Overview and Identification.
