This country is known for having iconic creatures that can be dangerous if confronted. These include moose, bears, wolves, and the surprisingly aggressive and mean-spirited Canada goose.\nHowever, there are smaller critters that can pose just as big a threat as some the larger mammals you might see wandering the woods in the summer.\nFor example, Canada is home to plenty of different snake species, most of them completely harmless, but did you know that at least two types of rattlesnakes call the great white north home?\nThe same goes for spiders. While most of the ones you'll find in Canada are generally harmless (if not really scary looking), one of the most infamously venomous arachnids also lives here.\nAnd just when you thought it was just the spiders and snakes that can cause problems for you, then there are the caterpillars. That's right, Canada has poisonous caterpillars.\nMake sure you keep an eye out for any of these poisonous critters this summer.\nBlack Widows\nView this post on Instagram 🕷️🕸️ H - A - Double L - O - W - Double E - N, spells Halloween!

They can be especially dangerous to children and the elderly.\nMassasauga Rattlesnake\nView this post on Instagram #massasaugarattlesnake #sistruruscatenatus #snakesofinstagram #rattlesnake #reptilesofinstagram #reptile #snake #zoo #zoolife #stlouiszoo #animalsofinstagram #coldblooded #beautiful A post shared by Wes G (@animal_wes) on Jul 15, 2017 at 6:54pm PDT\nThis particular species of rattlesnake, identified by its broad dark and light colouring.\nIt is only found in Ontario, and generally will not attack unless it has no other option. Still, it wouldn't be a great experience.\nPrairie Rattlesnake\nView this post on Instagram Your standard prairie rattlesnake. With @chrissid24 A post shared by Travis Raszkowski (@travisrazz) on Feb 5, 2020 at 8:36am PST\nThis second breed of rattler generally only lives in southeastern Alberta and southwestern Saskatchewan. Like the Massasauga, it will only bite as a last resort.\nWhile it's not necessarily deadly, this snake's venom has caused temporary parlysis, according to a Calgary Herald article.\nMurder Hornets\nView this post on Instagram Vespa mandarinia mandarinia (Queen Japanese Giant Hornet). 🐝 I received this stunning specimen from @carim_nahaboo a while back and it is by far one of my absolute favorite species of hornet out there! The striking coloration, enormous size and fierce looking face truly makes this species a icon of Japan’s Unique ecosystem! 🐝 #Hymenoptera #Apocrita #Apucleata #Vespoidea #Vespidae #Vespinae #Vespa #Vespamandarinia #vespamandariniajaponica #Japanesegianthornet #AsianGiantHornet #Hornet A post shared by Invert Aficionado (@arthropodian) on Apr 11, 2020 at 12:40pm PDT\nThese newly introduced behemoths are not native to Canada, but have instead made their way north from the United States.\nThey have become a problem mostly for local bee populations, but their sting can be incredibly painful and their venom can be overwhelming to humans if stung multiple times.\nHickory Tussock Moth Caterpillar\nView this post on Instagram Hickory Tussock Moth Caterpillar (Lophocampa Caryae). . . . Do not recall ever seeing one of these before, although I have definitely seen the moth. I decided to just snap a couple pictures of this cutie at Chittenango Falls State Park, and move on without harassing it further. After having read about it, I am glad I did. Apparently these cute little caterpillars have quite the chemical defense system. Sounds like they can cause significant allergic reactions with their venom. . . . #igmw_macro #just_newyork #newyorkonly #naturalnewyork #rustlord_unity #newyorkoutdoors #fiftyshades_of_nature #photograferz #hey_ihadtosnapthat #nikond7500 #ipulledoverforthis #pocket_allnature #pocket_usa #show_us_nature #nysdec #chittenangofalls #hickorytussockmothcaterpillar #icu_macro #ig_closeups #tv_closeup #friendsofstewartpark #newyorkstateparks #macroworld #macromood #just_unitedstates #macronature #gofingerlakes #fiftyshades_of_macro #ispyny #fingerlakeslandtrust A post shared by Chuck Metcalfe (@chuckmet) on Oct 4, 2017 at 6:09am PDT\nWhile a caterpillar is not likely to attack you, some of them, including the hickory tussock, excrete venom when they are touched.\nThis can cause itchiness, pain, or a burning sensation. Some people can even have severe allergic reactions to them. They are mostly found in southern Ontario.\nIo Moth Caterpillar\nView this post on Instagram Look who was chillun with the snake plants today 🐛🐛🐛 . . . . . . . . . #iomoth #iomothcaterpillar #caterpillar #nature #snakeplant #sansevieria #snakeplant #plantparent #plantmomma #crazyplantlady #florida #fall #plantmom A post shared by Gracie | Plant Mama | SPT 🌱 🇵🇭 (@plantyfilipina) on Nov 6, 2019 at 12:44pm PST\nThese types of caterpillars are very colourful and would make for a great photo, but you definitely want to avoid touching them.\nLike the hickory tussock, these critters excrete poison through hairs on their body. While it's not deadly, it can be as painful as a bad bee sting. They are found in southern Ontario, Quebec, and New Brunswick.
