(July 10, 2025) Last week, we began receiving reports of seeing the very first 4th instar nymphs of the year, and I have also began making my own observations while out in the county. The key identifiable characteristic that you will see is the color change from black with white spots, to red with black and white markings. The next stage that we will see will be the adults. Adult SLF have strong legs for jumping, just like the immatures, but also have wings, making them in more mobile.
