Oil Beetles
Perhaps it’s because there are so few blue plants, animals, or fungi in nature that they seem to really catch our attention. That is definitely true of this beautiful Oil Beetle (aka Short-winged Blister Beetle, Meloe angusticollis), photographed in eastern PEI earlier this month by Carla McKie. Oil Beetles get their name from oily, orange droplets that ooze from their joints when the beetles are threatened. That substance is haemolymph (insect blood), and it also gives the

Entolomatoid Mushrooms
Late summer and fall may be peak mushroom seasons on PEI, but spring has fungi to find, too! While checking my go-to spots for Morels this week, I found lots of these Entolomatoid Mushrooms (Family Entolomataceae). I often ignore LBMs (little brown mushrooms) as being too hard to identify and above my skill level. However, as I gain experience in mushroom identification, I’ve started looking for clues that point to the Family. If you’ve attended any of my workshops, you’ll

June Bugs
They’re baaaack! Here in Central PEI, the first Hummingbird and the first June Bug arrived within a couple of days of each other last week. Most people look forward to seeing the tiny birds far more than they do the shiny insects, but what exactly are June Bugs anyway? Let’s take a look! “June Bug” is a general term used to refer to many different species in the Scarab Beetle Family (Scarabaeidae). The ones found most often on PEI are the native Phyllophaga anxia, although at

Wild Lily-of-the-Valley Leaves
One of the nicest treats of a PEI spring is harvesting your own fresh, local food after a winter of stored root vegetables and imported fare. Fiddleheads, dandelions, cat-tails, dock, watercress, and magnolia – along with pheasant back and morel mushrooms if you can find them – are all in season right now. But if you’re looking for something new, give Wild Lily-of-the-valley (Maianthemum canadense) a try. Followers of my blog may remember that I introduced you to this plant

Edible Cat-tail vs. Toxic Iris
PEI has so many wild foods on offer in May: fiddleheads and nettle greens, burdock and primrose roots, morel mushrooms and pheasant’s backs, and so much more! Cat-tails (Typha latifolia) are versatile and easy to use, but it’s good to know how to tell them from a toxic plant of the same wet habitats: Blue-flag Iris (Iris versicolor). Cat-tails and Iris aren’t hard to tell apart in summer and fall, but it can be easy to confuse them where they grow side-by-side in spring (ma

Eelgrass
There’s one PEI plant that most people are very familiar with, but few have seen growing in its natural habitat: Eelgrass (Zostera marina). This is how most of us know Eelgrass: washed up along the shore. Eelgrass actually grows in extensive beds offshore as well as in our bays and estuaries, and – despite what you may think – it’s a true flowering plant and not a seaweed. Eelgrass has roots, stems, leaves, flowers, and vascular tissue (structures that move water and nutr

Edible Fir vs. Toxic Yew
It’s almost conifer-tip season, that time of year when we can enjoy the tasty, Vitamin-C-rich, new growth of our needle-leaved trees. While all of our conifer trees are edible, PEI does have one poisonous, native conifer shrub. Can you tell which of the needles in the photo are tasty and which are toxic? When it comes to conifer tips, White Spruce (Picea glauca) is the species most commonly used in the kitchen, as well as my personal favourite (you can find more details in

Geese and Mussels
The sound of Canada Geese is one of my favourite signs of spring – “goose music”, as Aldo Leopold called it. Their northerly migration is also marked by the return of feeding signs in PEI’s bays and estuaries, and some related behaviour that may surprise you! You may think of Canada Geese as herbivores that feed on aquatic vegetation and grasses in spring and summer, and the remnants of agricultural crops in fall. But, like many herbivores, Canada Geese are not strict veget

Marsh Marigold
As a botanist, I confess to teasing birders from time to time: groups of people flocking to the same spot to see an unusual species – really? But then spring rolls around and I eat my words as I make my annual pilgrimage to Miscouche to see Marsh Marigolds (Caltha palustris). Marsh Marigolds are neither unusual nor rare on PEI (and they aren’t Marigolds). This member of the Buttercup Family (Ranunculaceae) is found in wet, mucky soil, and so is more common in Prince and Kin

Baby Wildlife
Spring is a time of renewal, including for PEI’s wildlife. Early breeders such as Coyotes, Foxes, and Ravens have their young now, and others such as Snowshoe Hares, Striped Skunks, and Red Squirrels will follow soon. Our migratory birds are also returning and will make starting a family job one. This is an important time of year for wildlife, but it’s also the time of year when well-meaning people can do the most harm. Seeing young animals in spring and summer is normal an

Red Maple Flowers
It’s that time of year when many people are anticipating the first flowers of spring, without realizing that some are already here! We’ve looked at two of my favorite precocious plants – Willow and Beaked Hazelnut – but I also have a soft spot for Red Maple ( Acer rubrum ), flowering now. When we think of flowering trees, it’s often Apples, Cherries, and Serviceberries that come to mind. These showy species follow the usual order of things: leaf out first, then flower. But

Hazelnut Flowers
Some of PEI’s early spring wildflowers are showy, in-your-face sorts. Others are tiny, delicate, and go unnoticed to all except to those specifically looking for them. Today’s plant is in the latter category, and one of my favourites: Beaked Hazelnut ( Corylus cornuta ), flowering now. Hazelnut is a common, native understorey shrub found in mixed forests and along streams and trails across the Island. It stands out in the landscape this time of year, with finger-like male c

Black Knot Fungus
This is a great time of year to spot a PEI fungust that's best known as a disease of Cherry trees: Black Knot ( Apiosporina morbosa ). Black Knot fungus forms distinctive, black galls on stems and branches of our native Pin Cherry and Chokecherry, as well as ornamental Cherries and Plums. While it’s unattractive, reduces fruit production, and may kill the infected branch, Black Knot doesn’t usually kill the entire tree unless the infection is very severe. Within those black

Pussy Willows
One of PEI’s first botanical signs of spring are Pussy Willows ( Salix spp.). We have more than a dozen different Willows on the Island, but only one – Salix discolor – officially has the common name ‘Pussy Willow’. Willows are notoriously difficult to tell apart, but don’t worry: all our species are commonly called Pussy Willows this time of year so, right now, you can’t go wrong! Those soft, fuzzy balls are the male flower buds, called catkins. (Female catkins are sim

Flying Squirrels
One of my favourite PEI animals is seldom seen despite being fairly common: the Northern Flying Squirrel ( Glaucomys sabrinus ), shown here in a photo by Ron Serres (used with permission). Flying Squirrels are beautiful, large-eyed, soft-furred animals, with a flap of skin (called a ‘patagium’) running from wrists to ankles on each side. That flap allows them to glide 50 metres or more between trees in the forest and has been copied by the wingsuits used by some BASE jumpe

Lung Lichen
You may think there’s no old growth forest or wilderness on PEI, but that’s not true. We have amazing ancient and wild spaces if you know where to look and can recognize the signs. Lung Lichen ( Lobaria pulmonaria ) is one of those signs. A lichen is a unique creature: usually, it’s a combination of a fungus and an alga or cyanobacterium functioning as one organism. But Lung Lichen is one PEI’s few tripartite lichens: it includes a fungus, a green alga, and a cyanobacter

Pileated Woodpeckers
Some PEI wildlife signs are subtle, while others are hard to miss! These are the unmistakable holes of a Pileated Woodpecker. Pileated Woodpeckers are roughly crow-sized birds, with black bodies, white stripes down their necks, white patches on their wings (visible in flight), and a dramatic red crest on their heads. If you can imagine Woody Woodpecker, you’ll be in the ballpark: the Pileated Woodpecker is said to have been the inspiration for that cartoon character. Th

Cavity Trees
We’ve looked at needle-leaved and broadleaved trees this winter but standing and fallen dead trees make enormous contributions to PEI’s forests, too! Trees die naturally from a variety of causes: old age, disease, insects, fire, weather damage, or environmental stress, among others. The death of a tree is part of the life of a forest and is necessary for the survival of everything from plants, lichens, and fungi to insects, birds, and mammals. Insects such as Bark Beet

Duck Feet
PEI’s bird tracks come in five different forms. So far this winter we’ve looked at two: game bird (featuring Ruffed Grouse and Ring-necked Pheasant) and classic (aka ‘anisodactyl’, illustrated by a Bald Eagle). Today we look at the third type: webbed (aka ‘palmate’), with ducks as our example. The basic structure of webbed tracks resembles that of game birds, with three long toes pointing forward and one short toe pointing back. However, in this case, the three front toes a

Stoneflies
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
