Now that spongy moth egg laying is complete for 2023, it’s a good time to look for and dispose of the egg masses produced by adult moths over the past two months.

Spongy moth egg masses are tan-colored lumps about the size of a nickel or quarter, and can be found on trees, buildings and other outdoor objects. They may also be found in protected places such as firewood piles and birdhouses.

Whether you are headed out to a tree stand in your favorite local forest or a duck blind on the shore of your nearby pond, you can take a few easy precautions to help minimize the spread of invasive plants in your favorite hunting spots. / Photo Credit: NAISMA.org

Heading out to your tree stand or hunting blind this fall? Avoid adding invasive species to your hunting party by taking a few simple steps to help protect your woods.

Non-native invasive plants often outcompete native plants in forest environments, degrading diversity and destroying wildlife habitat. Invasive plants can replace local forest species and may interfere with or decrease tree regeneration. They may take over woodlands, prairies and wetlands, and many provide ideal habitats for pests that harm wildlife and people alike.

Scattered balsam fir trees in some areas of northern Wisconsin have suddenly turned rusty red to brown and are dying. These trees are not being impacted by spruce budworm and typically die with a full complement of needles.

The symptoms resemble what was observed in 2018 and 2020. So far, the number of trees being reported is smaller than what was seen in 2018 or 2020. Reports are still coming in, but they seem to be concentrated in northern areas of the state where we had extensive snowfall in late winter.

When a pile of more than 500 pounds of uncooked pasta was found in the woods in New Jersey in early May, no one was quite sure why or how the piles had appeared — but it was clear that they didn’t belong there.

Whether spaghetti noodles, broken electronics or old furniture, some things shouldn’t be in our woods, waters or roadsides, no matter the reason.

Though it may seem obvious that you should avoid dumping these types of waste in your local woods, some items aren’t as straightforward.

In many areas across Wisconsin, conditions were right for the worst outbreak of spongy moth caterpillars (Lymantria dispar) in more than a decade.

The caterpillars of this invasive insect — formerly known as gypsy moth — prefer to feed on oak, birch, crabapple, aspen and willow leaves, but will also feed on many other tree and shrub species. As of early August, caterpillars have pupated, but adult moths remain present.
