While most bugs are firmly hunkered down for winter, ticks will emerge and hunt for hosts any time the temperature is above freezing. If you spend time in the woods during the winter, remember to check your body for ticks if it was a warm or sunny day.

While bees are the best-known pollinators, other insects can also be effective pollinators, like this swallowtail butterfly pollinating common milkweed. Maintaining a diversity of native flowering plants helps most pollinators.
