Last year, Kentucky got to experience the group of periodical cicadas known as Brood X bursting onto the scene, singing their song, mating in trees, and dying in spectacular numbers. It’s like nature’s most morbid Mardi Gras. There were likely…
Every spring, people notice the presence of little red bugs walking on pavements, sidewalks, stones, or some kind of masonry floor in patios or outdoor walls. These are not insects, but mites and are commonly called concrete mites, cement mites,…
The good news is that trap captures of true armyworm and black cutworm moths are down considerably compared with last year at this time. Although it is important to note that we had to switch trap types in Princeton (metal…
