Wondering what those ½ inch pale brown moths are doing hovering in your porch lights or why they are even alive this time of year? They are called winter moth. The male and female winter moths emerge over a period of several weeks beginning in late November and continue through December. During this time, the moths mate and the females lay eggs on the trunks and branches of their host plants. There is absolutely nothing we can do at this time of year to deter them but just sit and wait until the eggs hatch in early spring. Please take note that these dull brown moths that are just annoyingly in your way as you are trying to get into your front door after a long days work are the dreaded little green inchworm that makes swiss cheese out of your plants early spring.
