Adult flies in the Syrphidae family are conspicuous day-flying insects that are very skilled at hovering, and love to frequent flowers, which led to their common names of “hover flies” or “flower flies”. They are brightly colored and are very abundant in many familiar environments. Many of the hover flies strongly mimic bees in coloration and sound and it is no wonder why many folks confuse them for being small bees or even pests. Continue reading

The sugarcane aphid has now been confirmed at low numbers in multiple counties in Lauderdale, Shelby, Hardin, Hardeman, Chester, and Henderson Counties.

Just a reminder that weekly moth trap catches in pheromone traps can be accessed by clicking on “Moth Trapping Data” under Quick Links on the left menu of our news site. This includes catches of bollworm (corn earworm), tobacco budworm, and southwestern corn borer. There is nothing exciting to report at this time, but be on a lookout for a spike in southwestern corn borer catches over the next two weeks. Over the past several years, this has occurred sometime between late June and mid July.
