Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. I’ve been receiving photos of deformed Chokecherry (Prunus virginiana) flowers from around the Maritimes, including this one from Tara Matheson here on PEI. The cause is a fungus, Taphrina confusa. Let’s take a look! Normal Chokecherry flowers have five white petals and grow in finger-like groups, called ‘racemes’ (inset photo). Once pollinated, each flower will form an

If you think the best thing about a PEI winter is the absence of insects, I have bad news for you: this is peak season for some of our invertebrates! Carla McKie recently sent me this photo of one the creepie-crawlies on the snow in Rock Barra, wondering what they might be. They are Winter Stoneflies, also known as Willowflies ( Taeniopterygidae Family). At first glance, you might think this is an Earwig out for a mid-winter stroll. Like Earwigs, Winter Stoneflies have six

Tracks and scat may be the most common signs of PEI wildlife, but they are not the only ones. Other examples include dens, nests, cavities, caches, browse, and this very cool adaptation: eyeshine. Not all animals have eyeshine, but those that do have a special membrane called the tapetum lucidum (Latin for bright tapestry) behind the retina – the light-sensitive part of the eye. Light passes through the retina and is reflected off the tapetum lucidum back to the light sourc

Last month, I posted about the advantages and disadvantages of multi-year needles versus annual broad leaves on trees (You can read about that here: https://www.pei-untamed.com/post/conifer-adaptations ). Some of you asked about Eastern Larch, a tree with a foot in each world. Let’s take a look! Keeping needles all winter does have a price: it allows snow to build up on the tree, placing tremendous weight on its branches. This can cause branches to break, or entire trees to
