What does this Warm Winter Mean for Insects?
Except for a few extremely cold days, Iowa has experienced a mild winter. In fact, February 2024 was the warmest February in Iowa’s weather history, and this winter is one of the warmest ever for the state. In addition to warmer temperatures, the total snowfall for our state has been low (Figure 1) and below average compared to a normal year (Figure 2). Much of the snowfall this winter was during a two-week period in January. As a result, many people are asking how a dry and mild winter might impact overwintering insects.
