In decades of surveillance, adult blacklegged ticks (Ixodes scapularis, female shown here) have only been found in fall months in Mississippi. But in 2022, 13 adult blacklegged ticks were collected between June and September in locations across the state, the time of year when previously only larvae or nymphs were found. Scientists sharing the findings admit: They’re quite puzzled. (Photo by Blake Layton, Ph.D., Mississippi State University Extension Service)
