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

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

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!

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

Woolly Alder Aphids

Meet Woolly Alder Aphids ( Prociphilus tessellatus ). From a distance, Woolly Aphids do look like some sort of fluffy, fungal mould on the branch of a tree. But take a closer look and you’ll see that those fuzzy clusters are actually dozens – sometimes hundreds – of individual insects crowded together. The

Holey Rocks

PEI’s shores are full of interesting finds, including holey rocks like this one. At first glance, you may think this stone was shaped by waves and tides, but the creators of these holes are biological, not physical. Rocks like this are sometimes called witches’ stones, hag stones, or adder stones, although those terms are more commonly applied only if one or more of the holes passes all the way through. According to legend, witches’ stones bring good luck by letting only good
