St. Lawrence County – look alikes

Imposters! The several possible spotted wing drosophila (SWD) females found in traps collected June 22-23 in St. Lawrence County, as reported on June 24, 2013, by Paul Hetzler, Cornell Cooperative Extension Association of St. Lawrence County, were SWD look-alikes.  Paul monitors a trap network mainly located in berry crops. Peter Jentsch's and Julie Carroll's programs verified the specimens were not SWD.

Compare the SWD female on the left to the look-alike female on the right. Once seen, the saw-tooth SWD ovipositor is unforgettable.
