When I first heard about murder hornets entering the United States, I assumed they were coming over our southern border, like everything else. Murder hornets sounded tropical. As it happens, though, they were leaking in across the Canadian border, from Vancouver, B.C., where they also don’t belong. They belong in east Asia, mostly.
Their proper name is Asian Giant Hornet, but that is an insufficiently inflammatory name for the modern media world. And now that we have all gotten familiar with the insect, we have to start calling it something other than Asian, because Asians are already being persecuted for too many things. Not by sensible people, but there are a lot of assholes out there and a lot of people profiting from stirring them up. Like a hornet’s nest.
The hornets are dangerous sometimes, and can kill a man if he’s allergic, or if he is gang-stung, just the kind of thing you’d expect from an illegal immigrant insect. Anyway, now he’s the Northern Giant Hornet. Although, since we’ve recently been informed we should be leery of Canadians, the “northern” bit probably doesn’t shine him up as much as one would like. It’s hard to keep up with the metastasis of prejudice.
Recently, the hornet has been declared eradicated in North America, which is cool.
That was because of a lot of good field work. Residents were educated to look for the hornets, and traps were set. They’re easy to spot. They’re huge—almost two inches long, for starters, plus the vertex is enlarged and the shape of the apex of the aedeagus is distinct. Really, just go with the two inches. They’re right up there with the rape aphids and felonious flies and the click-beetles of doom. We don’t want them.
They prefer a forest environment, and can be identified by the scraping sounds of hornet butt through the leafage. If tiny suitcases escape from its cargo section, that is considered diagnostic. So someone found one in a trap, hung a transmitter locator over its main fuselage with dental floss, and followed it back to its nest. Where they found several more stuck on the tarmac when the flight crew timed out. They killed them all and it’s been two years since anyone has found one in Washington.
It’s like polio, which had gotten down to a few dozen cases in the 1970’s and was weeks away from being eradicated but it kept blinking back on, and now that we know how horrible vaccines are, things are looking real bad again. Thing about murder hornets, you let one in and the whole damn family follows, because they lack that sense of rugged individualism that keeps Americans proud and free and utterly deprived of good health care.
The American spirit in all its forms was evident in the postscript to this tale. The last hornet nest, eradicated, was returned to the owner of the property it was on, per his request, and he advertised it for sale. A beekeeper bought it and donated it to the state entomology team to study.
Still, it’s a hopeful sign that our murder hornet scare is a thing to put in our rearview mirror. Or it could have been. Sadly, word on the street now is that Robert F. Kennedy Jr. plans to reintroduce them, having learned that a paste of their crushed abdomens applied to the skull draws out brain worms.
They really do use glue and dental floss. Incredible.
Around here, phorid flies have been in the news. This is a tiny, harmless fly that uses mushroom compost to lay its eggs. The flies have had a population explosion that has driven area homeowners nearly frantic.

Oh! Glue! I just read “dental floss” and somehow pictured they were tying it around their abdomens in some way like wrapping a present. I feel better now.
The biggest problem here in Delaware, insect-wise, IMHO, are mosquitoes. Especially with climate change, their season has been extended. And they love me. They are all over me like MAGA on Trump. So I have a limited time to do anything outside, and don’t think that I don’t use that as an excuse not to do anything outside. Because I totally do.
There used to be all this drama about Lantern flies for a while. There were a lot of them for exactly ONE year. I actually enjoyed stomping them, and it was encouraged. That first year, I remember going to a strip mall, seeing them everywhere, and spending more time stomping than shopping for what I actually came there for. There were fewer with each succeeding year. Last year, I saw maybe two. No stomping involved.
My theory: My understanding is that since they feed on tree sap — which is sugary — they must taste sweet. Like tiny jelly donuts. We get a LOT of catbirds around here in the summer, and they are adventurous eaters. And they love fruit, which is sweet. Ergo, I think someone tried it, loved it, and told the rest of their flock. Catbirds are one of my favorite birds, primarily because they are obviously so curious. They look through my window (not in a creepy way), they watch me when I take out the compost. In fact, usually the first time I see them each year is on the fence by the compost pile. We used to have more Mockers than catbirds around here, but now it is the opposite. Climate change, I guess. Just like the way we used to have only Turkey Vultures, but now Black Vultures (which like warmer climes) have replaced them. I love them all, mind you, but it is a bit disconcerting if you know anything about birds and their migratory habits.
We don’t have any here, I don’t think, but a lot of these things come in and flourish because they have no enemies and then things crash and new predators show up and people stomp on them and it dies down for a while. What do I know? Happy stomping! They’re cute little buggers though.
I hope the native Eastern cicada killers/cicada hawks aren’t persecuted by those who might mistake them for murder hornets based on their similarly monstrous size.
Mimi, I’ve noted a similar reduction in numbers of SLFs. I don’t know about what they taste like, but they do excrete a sweet, smoky flavored substance which local nectar feeders enjoy to such an extent that honey produced from it has a distinctive and apparently not unpleasant flavor and color.
Cool! I knew that you’d have some input about them! The reason I know they’re sweet is that i had read in the paper that when you smoosh them, you should immediately wash it away, as the sugars left behind could cause a mold problem. Of course I never cleaned it up, and never had a problem with mold beside what we already have in Delaware because we’re so humid. Nice to know about the honey; I’d definitely try it!
Their tree of choice is the exotic and highly invasive ailanthus, which was originally planted as food for imported silk moths. Ailanthus has a musky scent. It’s been compared to rotten peanut butter, but I’ve never had rotten peanut butter, so can’t say. Anyway, I find the ailanthus scent unpleasant, not quite as bad as stink bugs, but close.
Clerodendron smells like rotten peanut butter too. Mildew isn’t our state fungus, but it ought to be. At least we DO have a state fungus.
I think I’m infested with click-beetles of doom.
What size are they? They were more common in my old neighborhood than here, which is bizarre because that was a suburb and here I back up to woods.
I’m sorry, is that question “What size click-beetles of doom are they?” Because that would be awesome.
That would be awesome! In NJ we have eastern eyed click beetles which are nearly two inches long. I consider that huge, but then I’ve never been to the tropics. The eastern eyed has a click loud enough to bring dogs running. But that’s all they do. Click!
I found a black widow spider one night when I heard a click beetle clicking away out in the Pine Barrens. Sounded like a little clock. It had blundered into her web in a shallow overhang and was snapping its thorax as she was setting about wrapping it up.
Click beetles come in a variety of fun sizes from very large (to my thinking) to very small (I think most would agree). They all click.
I was curious what size our friend considered to be the click beetles of doom.
I just thought saying ‘click beetles of doom’ sounded so cool. If they were of ‘doom’ they would have to be large. Very large. And doomy.
As usual; Fabulous!!
When checking to see when these hornets were last seen in Canada, I found this: “DNA evidence suggested the populations found in British Columbia and Washington were not related and appeared to originate from different countries. There also have been no confirmed reports in British Columbia since 2021, and the nonprofit Invasive Species Centre in Canada has said the hornet is also considered eradicated there.” (AP)
So, they all may still have come into Vancouver BC on shipping containers but some stayed while others flew south through that undefended border.
Pretty soon, every single thing will be every single where.
Some of my entomologist friends (and also some of my ornithologist friends) have very firm feelings about exotics. If they don’t belong somewhere they should be exterminated.
I sort of leaned that way, but recently seeing how stressed all the biota is, it seems to me if they can survive in their new digs (without killing off everything else) they should be allowed to continue.
My entomologist friends will kill Chinese mantids on sight, noting that the Chinese do kill the native Carolina mantids. While this is true, if we kill off the Chinese, we might end up with no mantids. I’ve been observing mantids for most of my life and most I’ve seen are exotic. Partially this is because Carolinas are small and cryptically colored and partially this is because there just aren’t that many of them.
I used to look forward to seeing the Chinese mantids arrive each spring as nymphs and then grow through the summer. The last few summers I haven’t seen them at all.
Are those the mantids that are big enough to eat a hummingbird?
That is not a video I can evict from my memory.
Yes. The females can be quite large. It’s a shame we can’t upload photos to this blog. I hosted a Chinese female one fall. She understood I was her food source and would climb up and sit on my head. I was curious to see how long a mantid could live if kept warm, watered and well fed. Unfortunately they have self destruct written into their genes. She laid her eggs and when she was done, she fell apart. Her feet lost their hooks, then her legs fell apart and then she was dead.
Did she die ON YOUR HEAD?
Hey Murr: No, she didn’t die in my head. I forget whether I found her dead in her terrarium or I euthanized her when I found her too broken to function.
I used to see mantids all the time in the summer. I haven’t seen any in years. I don’t know their ethnicity, nor do I care. I only know they are cool! I mean, WHY are they not in a sci-fi movie??? Giant ants? Yawn. The Fly? Zzzzzzzzz….. Mantids already look like they’re from another planet, so they have a leg up on all other insects. I wonder what would happen if, in a movie, they were pitted against the giant spiders from The Lord of the Rings? C’mon, people… we have a concept here! Let’s run with it and get this movie done!
Two legs up!
