European Hornets in Muskoka
Ah, Muskoka in the spring – the promise of summer, warm breezes, and, oh yeah, hornets. If you've noticed some big buzzing beasts lately, you're not alone. Given all the hype around, it's high time we had a little chat about them.
There exists more than one large hornet in Muskoka, but we have seen an influx of one in particular this year. What we've been seeing is the European Hornet (Vespa crabro). And just so you know what we're talking about when we say large, here is a size comparison to the common wasp.

Pretty terrifying huh? We'll save you the trouble of reading the whole article and let you know right off the bat that it's pretty harmless and has been in Ontario for a long time. It's just more prevalent this year. But European Hornets do have a scary doppelgänger, "Murder Hornets" officially know as the Norther Giant Hornet or Japanese Hornet (Vespa mandarinia). Spoiler alert: You can stop having unnecessary freak-outs because we don't have 'em in Ontario.
Let's go through a little comparison so you can know the difference and avoid any pointless insect slaughter.
Meet the Hornets
European Hornets (Vespa crabro)
This species was accidentally introduced into eastern North America more than 160 years ago and today it is common in parts of Ontario. It is a very large wasp (2.5-3.5 centimetres), but smaller than a northern giant hornet. They fit right in and seem to enjoy Muskoka as much as we do.- Size: Workers range from 1 to 1.5 inches, with queens slightly larger.
- Colour: Reddish-brown head, yellow face, and a body decked out in brown and yellow stripes. The darker stripes have a "tear drop" shaped appearance.
- Behaviour: Not as quick to anger as their Asian cousins, but they will sting if you tick them off. They’re night owls, buzzing around lights when other wasps have called it a night.

Northern Giant (Murder) Hornets, aka Japanese Giant Hornets (Vespa mandarinia)
Let's address the "murder hornet" moniker. Media hysteria, anyone? Sure, these guys are big – the largest hornets on Earth, in fact. Native to Asia, they're about as subtle as a chainsaw in a library.
- Size: Queens can reach up to 2 inches. Workers are a solid 1.5 inches.
- Colour: Picture a bright yellow/orange head with big black eyes and a dark body streaked with yellow/orange bands.
- Behaviour: Venomous stings and aggressive tendencies, especially around their nests. Plus, they have a nasty habit of decimating beehives – not great for our ecosystem. But, relax, no confirmed sightings in Ontario yet

Identifying the Differences
-
Size and Appearance:
Northern: bulkier.
European: are a bit more streamlined. -
Coloration:
Northern: Bright yellow/orange heads with dark bodies.
European: Reddish-brown heads and striped abdomens with teardrop-shaped dark bands. -
Behaviour:
Northern: Aggressive, bee-killing machines.
European: Mellow until provoked, more common in Muskoka this year.

Why the Fear and Confusion?
Blame it on the media blitz in April. Those "murder hornet" headlines had everyone seeing monsters in every buzzing bug. It's easy to panic when you don't know what you're looking at. European hornets, despite their size, are more bark than bite. They're more common this year, but usually harmless if left alone.
What to Do If You Encounter These Hornets?
Stay cool. If you spot a big hornet, don't go all Rambo. They usually mind their own business unless provoked. Keep your distance, avoid sudden moves, and let it buzz off. Got a nest problem? Don't play hero – call in the pest control pros.
And about those Northern giants – the Ministry wants any large hornet sightings reported, even though they're not confirmed to be here. We're not even sure these hornets could handle Ontario winters.
Fun Facts About Hornets (Yes, Really)
Believe it or not, hornets have their perks. They munch on other pests, which can save your garden from ruin. They do a bit of pollination while feeding on nectar. And, while they might not be cuddly, they're an integral part of our ecosystem. Just checking if you're still awake with that last bit.
Stay curious and calm, Muskoka!

Captured one at our cottage just outside Bracebridge last week . I sent in a report as FB has been asking people to send in sightings with back and side views . Caught one last year also but can’t find nest . They are large and noisy.

I captured and reported a Giant Hornet last week. Our cottage is located North of Parry Sound near Georgian Bay. This wasp is over 2 inches long and matches the colours in the example. No stinger is visable. Waiting for reply from the report I submitted

I’m almost absolutely certain there was a Northern Giant hornet nest at my friends cottage last year. I have reached out to him to see find out if it’s back this year – if so I’ll suggest he report it to the ministry.
They were more orange and very full bodied, and looked in every way much more like the Northerns than the Europeans.
This was in Sunridge, Ontario
