Yellow Garden Spider
Fall is peak spider season on PEI, and the most commonly-reported of our nearly 200 different species is the lovely Yellow Garden Spider (Argiope aurantia). If you are among the 6% of the population that experiences arachnophobia – fear of spiders – you may not be happy with either today’s photo or my reference to just how many species the Island has. And, if that’s the case, you really won’t like me mentioning that one UK researcher estimated that there are as many as two mi

White-margined Burrowing Bug
I love getting questions about the wild side of PEI and so was thrilled to get this photo from Megan Jones. She found this clump of bright red insects in some old straw near her barn and was curious about their identification and whether they could be invasive. These are the lovely – and native – nymphs of the White-margined Burrowing Bug (Sehirus cinctus). Let’s take a look! You could be forgiven for thinking these are Lady Beetles at first glance, given their similar red-

Sea Stars
PEI has many interesting wild animals, but some of the most beautiful – and unusual – are Sea Stars, often called Starfish. The waters around PEI are home to at least five species, including the Common Sea Star (Asterias rubens) and Forbes Sea Star (A. forbesi). It’s not hard to see where these invertebrates get their name: ask any kindergartener to draw a star, and you’ll get something that resembles this five-pointed shape. While our most common Sea Stars do have five arm

Horse Flies
I would have liked a better-composed and more in-focus photo of today’s PEI animal, but I was under attack by a hoard of these fierce creatures. If you’ve met them, you know what I mean: these are Horse Flies (Tabanus nigrovittatus or similar). The names Horse Fly and Deer Fly are often used interchangeably for any large, biting fly, but they are two different, albeit related, beasts. Horse Flies and Deer Flies are in the same family (Tabanidae), but Deer Flies (Chrysops sp

Jellyfish
There are certain, shared experiences that unite those of us who grew up on PEI. For example, getting storm-stayed in winter, going to the beach in summer, and having annual run-ins with Jellyfish! There are at least three species of Jellyfish in the waters around PEI: the Lion’s Mane (Cyanea capillata), shown here, the smaller and more cinnamon-coloured Atlantic Lion’s Mane (Cyanea fulva), and the white Moon Jelly (Aurelia aurita). Of the three, the Lion’s Mane is the most

Fireflies
We humans tend to divide insects into two camps. There are those we don’t like (Earwigs, I’m looking at you!), and those we do, with no better example than Fireflies. I captured this lone Firefly’s flash at my home in central PEI recently and thought it’s time we took a closer look at these interesting insects! Fireflies are beetles, not flies, and not all have ‘fire’ – many species are daytime-fliers that use pheromones, rather than light, to communicate. The night-flying,

Melanistic Red Squirrels
Wildlife doesn’t always follow the rules, and despite their name, Red Squirrels are sometimes black. PEI has a higher-than-average number of black-furred Red Squirrels (such as this one photographed by Dave Campbell), so let’s take a look at this phenomenon! In mammals, skin and hair colour are determined by how much and what type of melanin is produced. Genetics controls melanin production, and most individuals within a species have similar colours: for example, Skunks are

Virginia Ctenucha
Welcome to Insect Appreciation Days, celebrated from June 8 – 13th annually, thanks to the Entomological Society of Canada. And what better insect to profile than PEI’s most commonly-reported moth, the Virginia Ctenucha (Ctenucha virginica)! First, what’s up with that name? Ctenucha (ten-OOO-sha) comes from a Greek word for ‘comb’, and refers to the feathery, comb-like antennae of the male moths. (The individual shown here is a female, with more wiry, less feathery antennae

Ruby-throated Hummingbirds
With their tiny size, fearless personalities, and amazing agility, Hummingbirds capture our imaginations in a way few other birds can. PEI has only one species – the Ruby-throated Hummingbird – and their time with us is as short as an Island summer: from roughly Mother’s Day to Labour Day. Hummingbirds are creatures of extremes. They’re our smallest birds by far, weighing just a few grams (or about as much as a Canadian nickel); it would take more than 1,000 Ruby-throats to

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

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

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

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

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

Eyeshine
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

Bald Eagle Tracks
Pop quiz: what’s the largest winter wildlife track you’ll find on PEI? Coyote is our largest animal, so that would be a reasonable – but wrong – guess. Snowshoe Hare’s hind feet are pretty big, but not the largest. The honour goes to an animal you may not have thought of: the Bald Eagle. When identifying bird tracks, toe arrangement is a helpful starting clue. Here we see three long toes pointing forward and one long toe pointing back, in what’s called the classic (aka ani

Grouse vs. Pheasant Tracks
Birds may not be the first animals that come to mind when you think winter wildlife tracks, but some of our avian neighbours spend more time walking than flying. Two good examples are Ruffed Grouse and Ring-necked Pheasant. When identifying bird tracks, toe arrangement is a helpful place to start. Here we see three long toes pointing forward and one short toe pointing back in what’s called the Game Bird arrangement. Only four PEI bird species sport feet like these, and so r
