They are also one of the most vicious killers of mosquitoes, both in their larval and adult stage. Definitely deserves the "Best Insect" award.

Crane flies also attack and kill "skeeters." But they are not graceful fliers like dragonflies and damselflies.

Their wings are loud like hummingbirds. I use to try to splash them in my pool as a kid. Way too fast

And they are one of the few insects to have survived from the age of Dinosaurs. There used to be Dragonflies with 2m wingspans.

​@@davidboydarnott417 imagine hornets from that era... (if there were any that is) scary...

So you saying that the Guy should smash one of the hornet with the plastic Dragonfly?

@@zquackyyes

@@Peppermynt. Smash*

Or make a drone that can completely act like a dragon to fly (fighting, wing flapping, it's noise, ect) to convince them to go away...

@@anthonyfloyd2327 no, *SMASH*

only problem with that is if it were to touch the honey bees it would fry them

@@shadowreptile001 They were staying away from it from the beginning. It seems to be the threat for the hornets.

​@@beebob1279 Still not a good idea...once the Hornets leave, the Bees will come back out and inevitably touch the figurine...I guarantee that you'll have more dead Bees than Hornets with that method. 💯

A potential idea would be to use a bit of tech using not only a small camera but also a microphone, attached to a raspberry pi and programmed to only turn on the current when detecting the hornets specifically within range by wing vibration tones and visual recognition programmed into it, set a specific bait trap that only the hornets would be attracted to that honeybees won’t go after (such as protein), and a tiny speaker connected to output a sound that the honeybees ignore but attract the hornets. If set up a meter away from the hive in weatherproof housing and on solar-powered rechargeable batteries, especially if you have multiples of them surrounding the hive, it could work well to lure and kill only the hornets and otherwise inactive when only the honeybees are around and touching it. In fact, the housing for the battery, raspberry pi, bait, speaker, camera, microphone and solar panel can be constructed from similar beehive box wood materials on a much smaller scale with fake entrances to fool even the smarter hornets, if honey is also used in the bait but the fake mini hive housing is sealed enough to prevent honeybees from entering it despite scent holes in the sides.

Or a laser

Or are the hornets just smaller?

​@@mickmuzzmkmz1628Brother we saw the Hornets migrate to USA we already know.

Though, some bees that would be fascinated by the figurine would also be zapped. Maybe an off/on mode could solve that?

You could probably train a neural net to identify when a hornet is touching it using a camera.

I like how it stares at the one that flies away as if asking whyd he fly away before turning around lmaoo

It is mentioned in video that the Dragonflies attack bees as well i am afraid that something like that can cause more trouble then it prevents.

Yes. Works with normal sized hornets. Should be okay for big hornets too.

Identifying the hornets shouldn't be too difficult, but a laser system would probably be too complex, since it would need to aim. Maybe electrify the dragonfly instead when a hornet is detected.

It seems to me that aiming with a laser will not be too difficult if you determine the parallax of the camera and enter coefficients to calibrate the aiming point. I think that hornets will not always attack a dragonfly and can get used to it, which will make the electric fly swatter in dragonfly useless, laser protection will not allow this. Although this looks much more complicated, it will also solve more problems.

Or pet a real dragonfly

They swarm though. People have died from them. Look up what injuries from their stings look like. Oof

Feels like a drop of molten metal on your skin. More than a few stings can kill.

those hornets over there are like yellow jackets in the US.. they are everywhere and with rather large colonies.. if you kill one, the pheromone it gives as its dying will draw dozens if not more to the spot where it was killed.. the beekeeper would never be able to kill them all to the point there is no more distress pheramone .. thats why when you watch the videos where they use glue sheets that a hundred hornets end up on the sheet.. it attracts more rather than stops the attack..

Some bees have a defense technique against giant wasps too, they swarm it then unleash all their body heat (though I believe it's usually against the scouts)

@@KillrMonkey19 It works, but is more of a desperate last resort defence tactic, when beehive is raided. Essentially pulling a last stand that may or may not save the hive.

Interesting. My mom believes that they're also a sign of good luck. I do agree with that they're cool insects.

Glue traps, usually for small mice.

A video was made about this before. Carelessly putting down a sticky trap is just as bad for the honeybees. The trick was to gravely injure a hornet, put it in the trap, then watch as other hornets come to investigate and get stuck in the same trap. But if this figurine worked, the manual step of capturing and injuring a hornet would not be necessary.

I think giant hornet would kill a mantis one by one, if mantis does not ambush. Those huge armored grasshoppers on the other hand won't be bothered even by a group of hornets.

"carnivorous katydids" I've never heard of those and I'm not sure I want to know any more.

@@simeonellinger2064 just know they aren't like your average grasshoppers

No they likely think the hive is weak because of the lack of bee pheromones and small response from the bees because there aren't very many bees in that hive. Less bees means easy target. If you kill a hornet, the rest will swarm the area in response. Be prepared to flee for your life, they're deadly.

it would have to be strong material since the hornets have strong bite force

It would have to be an ENORMOUS greenhouse, like at least an acre, if not more, in order to grow enough flowers to support a hive. Each flower only has a couple microliters (one thousandth of a ml) of nectar, so the hive would need several hundred thousand if not millions of flowers to support it. And don't forget, bees need pollen too. And let's say we could build a greenhouse that big. We'd have to make sure every tiny opening was sealed to keep the hornets out. And we'd have to check it several times a day. Not possible because we'd have to supply the water and keep it ventilated with giant fans to keep it from overheating. It'd be extremely expensive. I don't know about you, but I'd rather not have to pay $1000 for a jar of honey😊

@@scibear9944 that's a good point 👍🐝 so I guess it wouldn't be able to sustain much so maybe smaller. But more to protect the main hive bees and the bees could get out more entrance area so bees could escape the hornets. But I was thinking the bees could come out but it was supposed to sustain a little more, thanks for telling me anyway tho😁

These hornets can and have chewed right through wooden hives. Hives need to be made of or faced with metal. And even if a hornet gets in, Japanese honeybees (not European/American honeybees, tho) have a defense mechanism where they rush the hornet and form a "bee ball" around it, vibrating their wings like crazy. This causes the inside of the ball to heat up to around 115 degrees F, which the bees can tolerate but cooks the hornet. Unfortunately this defense only works against one or two scouts. If hornets attack en mass they kill all the adult bees and steal the babies to feed their larva back at the nest. It's kinda sad, really.

@@scibear9944 looks like he had some metal on the entry ways that only the bees could fit through…so at least they had that going for them…

@MrMan5014 Yes, I saw that. The thing is, if an entire swarm of hornets attacked the hive, they would indeed chew a new hole somewhere else, and they could probably do it in about five minutes. But unfortunately metal hives aren't really an option, since it would cause overheating in the summer, especially in Japan, which is known for its hot and humid summers. As I mentioned in another thread, I don't see why beekeepers don't erect hardware mesh fencing several feet around each hive. The mesh would be large enough to allow bees but too small for hornets. It'd be pretty cheap and easy, too.

Extra heavy duty bee suit😊

@@scibear9944 But his hand is free

@@lateblossom AH yes...that is true😆😆😆😆

It was an experiment, to see if the model would scare the hornets. This experiment mostly failed, but it’s nice to share the knowledge.
