As fall settles in and hunting seasons start to open across the state, many Wisconsinites’ thoughts have turned to tree stands, blinds and all things hunting.

Planning out your perfect capture means giving yourself the best chance possible, whether slipping into or out of your tree stand or ground blind. One popular idea is camouflaging your path – using plants or trees as a natural blind so you can reach your spot without being seen by deer or other animals.

Callirhytis piperoides is a gall that seems to erupt from an oak leaf’s midrib and can be on top or bottom of the leaf. It is found on the leaves of young northern red oak. Galls will fall off the leaf so that the insect can complete its development within the gall on the ground. / Photo Credit: Linda Williams, Wisconsin DNR

Have you noticed any galls on oak leaves or twigs? Don’t be too surprised. There are many different types of galls that form on oaks – some are smooth, some are spiky and others are fuzzy.

The native insect known as fall webworm (Hyphantria cunea) is back in the news.

The caterpillars don’t draw much attention on their own; instead, what catches the eye at this time of year are the large webs (or “tents”) that they create on the tips of tree branches.

Pine false webworm (Acantholyda erythrocephala) is not a very common insect in Wisconsin, but damage from larval feeding can occasionally be seen. The insects prefer to feed on white pine in Wisconsin, although reference material says they will also feed on red pine, jack pine and scotch pine.

Damage was reported as minor in the central part of the state from 1953 to 1961. In 1995, 1997, 2002, 2004 and 2006, it was once again observed as a minor pest feeding on red or white pine in the central part of the state, particularly Portage, Waupaca and Waushara counties. In 2024, a few scattered young white pine trees in Oneida and Vilas counties were observed with significant defoliation.
