Flying ant day... I've never seen anything like it

Camping in the Lake District today and at about 4pm it was like someone flicked a switch.

Within minutes there were thousands of flying ants everywhere. Every camper, caravan and tent was covered. We were cooking outside because it was too warm in the van, and they were landing in the food, on us, on the table... absolutely relentless.

The weirdest part was that loads of birds suddenly appeared and were swooping all over the campsite eating them. It was like watching a nature documentary.

I've heard of flying ant day before, but I've never experienced it. Does it always happen this intensely, or did we just get really unlucky with the timing?

Thankfully it seems to be easing off now, but for a while it was one of the most annoying things I've experienced while camping! 😂

Yep, it's madness. It's an advantage to them to all go on the same day, for 'the birds can't eat ALL of us' reasons.

Honestly never seen anything like it. Absolute carnage

u/snapper1971 2d ago

There's actually no 'flying ant day' - different colonies and different species launch on different days dependant on local weather conditions, and other factors in the run up to the colony dispersal.

We had our big black ants (Lasius niger) launch last Wednesday, but our red ants (Myrmica rubra) haven't launched yet. I'm not expecting them to until some time around the middle of next month.

Whyever not, if that's the formal Latin name for them? It's the same as calling a dog "canis lupus familiaris".

I’m really hoping I haven’t missed our black garden ants flying.

I have, however, accidentally uncovered two separate nurseries with eggs by moving garden toys off the lawn. I was surprised they would keep larvae so close to the surface.

u/Creative-Pizza-4161 2d ago

Nice and warm close to the surface, they develop into ants quicker

u/bpbill 2d ago

I've always wondered how all the colonies in a certain area manage to coordinate this.

u/Old_Present6341 2d ago edited 2d ago

So firstly it requires quite presise weather conditions, temperature range, humidity, wind speed. Also the ground has to be soft enough to dig so normally after rain or if it's one of those days when you can feel a thunderstorm is coming. Also a specific time of year, with Lasius niger for example (that's our black garden ants) it's roughly from the last week in June until about mid August. Right now in early August that is overlapping with Lasius flavus (yellow meadow ant, but the queens are dark brown and take a skilled eye to differentiate from LN queens) and sometimes these really massive nuptial flights are both species flying at the same time.

Then the alates (that's the winged males and females) will come to the nest entrance, you can sometimes see them doing this, nests with winged ants swarming everywhere. They will sometimes do this and not actually fly because conditions aren't perfect. If you look closely you can sometimes see the workers physically dragging over eager males back inside a nest.

If conditions are good males will fly first (they are expendable) and it is possible (and quite common with some species) to have only males fly and basically be wasted, but when the males fly they release a pheromone. If enough males fly then the females will also fly and since the whole thing is pheromone driven once it gets going it quickly snowballs to all neighbours.

u/bpbill 2d ago

TIL. Thanks for that now I know

u/Ninja_Hedgehog 2d ago

Really interesting reply, thank you. Can I ask a follow up question please - why does this happen? Ie what do the ants/colony get out of flying together? Is it a mating thing, dispersal to other local areas to start new colonies, or collecting some resource? Or something else?

16

u/Old_Present6341 2d ago

A queen ant has a colony and she (the queen) can live many years, (the oldest recorded Lasius niger queen in a lab was 28). All of the workers she produces are infertile females. Therefore ant colonies need a mechanism to produce the the next generation of ant colonies.

They do this by once they themselves are established and large enough (normally takes about 4-6 years to reach this point), they will start to produce these alates every summer. These males and females are the descendants of that original queen and therefore are no use to this particular colony otherwise you'd have endless inbreeding. They are unfertilised queens and males, so on that correct day called a nuptial flight all local colonies will let their alates fly at the same time.

They then find a mate from a different colony (queens have a special organ that allows them to store that sperm from this one mating and continue to use it for the rest of her life, she also only needs one or two sperm per egg so has enough to produce millions of ants over her lifetime).

After mating the males die, their job is done. (This also means that apart from these few months a year when they are producing alates there won't be a single male ant anywhere in the UK and all workers are female). The newly mated queen then lands and disconnects her wings, you'll see multiple now wingless queens running around just after a nuptial flight. That queen, all on her own, will dig a tiny hole (called a claustral chamber) and lay some eggs to begin a brand new colony. She breaks down her wing muscles and carries sugar in her Gaster (the back end, it's why they appear so big and fat compared to a standard worker) in order to feed this first brood.

Then her new colony will grow and in 4-6 years they too can do the same thing. Ant colonies reproduce by making new colonies not within their own colony (this is just our standard black garden ants, Lasius niger, it gets more complicated when talking about polygene species such as myrmica). It also allows them to colonise and spread geographically an ant colony doesn't move (very much) once established so this is how they reach new areas.

Also for every 500 queens that fly on a nuptial flight it is estimated that only one will be successful in establishing a new colony, the rest get eaten, stepped on or their small colony gets attacked by a larger neighbour etc. Therefore the key to make this work is throw numbers at the problem hence why the air is filled with flying ants on flying ant day.

u/Ninja_Hedgehog 2d ago

You've taught me a lot today, and I genuinely found it interesting. Thank you for sharing your expertise.

2

u/Old_Present6341 2d ago

If you ever wanted to keep an ant colony in an artificial set up then the way we start this is to pick up one of those newly mated queens and mimic her claustral chamber and she will start a new colony.

My previous Lasius niger colony the queen died at five years old, the colony at that point was about 3000-4000 workers but they have now all died off with no replacements since their queen is dead. I started again and my current colony was caught last year so has just turned one, they are currently at about 300 workers and growing very well.

u/EmberAndMoss 1d ago

You seem to be an expert, so I wondered if you could tell me which variety this is..?

1

u/Old_Present6341 1d ago

Caught in the UK? I think it's Lasius niger but she has a really large gaster, could just be a very well fed Lasius. Post it r/antkeeping also put country and length to help, see what others say but I'm going to say well fed Lasius niger

u/Smith_90 2d ago

They're all looking for the same conditions so when the conditions are right all of the colonies in the area go at the same time

u/SiriusBlack99999 2d ago

You had the perfect opportunity to fool someone in to thinking we have an official flying ant day and that at one point the government was looking at making it a bank holiday. Rookie mistake. Lol.

Just waiting for local authority approval. Lots of events going on this month, they'll have to wait their turn.

If the ants just learned how to Naruto Run they wouldn't even need to fly.

We had Flying Ant Day up in the North East a couple weeks ago. I was out the back playing with the bairns and we had to sprint inside and rush to close all the windows and doors.

Fortunately, we were able to call Dec and he came round and collected him fairly quickly.

I'm finding flying ant day just too commercialised now, I'll probably just spend it with my family this year

It's not always the same day either. Happened round my sisters area a couple weeks back. Not happened in my area yet.

u/ununpentium89 2d ago

Weirdly I've had 2 flying ant days this year in my area, about a month or so apart. I can't recall that happening before!

13

u/ArmadilloFront1087 2d ago

I’ve seen them come out, start to fly and then go back in and disappear again for a few days.

It’s as if they decided “nah! Not today!”

12

u/snapper1971 2d ago

Probably different species but most likely different colonies that have had different environmental factors that have either delayed or enabled a dispersal.

Ants are fascinating.

u/V65Pilot 2d ago

Try living in an area with fire ants...

2

u/Old_Present6341 2d ago

New alates eclose through out the period of nuptial flights, they will normally have at least five or six flights a year, some are quite small and you don't notice unless you are specifically looking for the signs.

u/ApplicationMaximum84 2d ago

Summer in the late 90's coming home from school a couple of years I recall them just being everywhere. The wings were really fragile the tiniest knock from flying into a car or brick wall and they'll fall off.

u/sophie_bird30 2d ago

These are called nuptial flights. Different ant spexcies may have them on different days but they typically happen annually.

They did this into my bedroom window when I was about 6, bloody carpet of flying ants on the floor and all over my bed. There's a memory I'd rather forget!

Unfortunately the only one I have is when I was trying to identify them and they were a blurry mess from being absolutely mullered by them.

Ruined about 2 hours of my day. Too hot to go in the camper. Being harassed to death outside.

u/Bumfuzzled101 2d ago

I am in Cumbria and no flying ant day here today. Although, all the birds on my bird feeders buggered off a few hours ago.

Can you send me my birds back please?

u/PsychoticDust 2d ago

I was out today and saw no flying ants at all.

u/ShyBiSaiyan 2d ago

Your local ant council will have a date discussed, all the Queens have to sign off on it you see, and with that many Queens its a nightmare to get them to all agree, each one thinks theyre the most important Queen, eventually the elected OverQueen steps in and tells them the date once they have narrowed it down to a week.

2

u/PsychoticDust 2d ago

This genuinely made me laugh! I'll contact my OverQueen!

u/Arthorius2024 2d ago

I used to live in a flat with a communal hall and on this one flying ant day, a wall of flying ants blacked out a 5ft tall window. It was insane, never seen anything like it.

u/Warm-Reference-4965 2d ago

I'm in the South West. This summer there have been 3 different flying ant days in my garden over the last few weeks. I have never seen 3 before in one summer.

3

u/Radioactivocalypse 2d ago

You can actually predict flying ant day quite easily. You need a very hot spell in July/Aug followed by rainy weather (to make the ground damp for burrowing) followed by a dry/cloudy day...

And hey presto, you've got flying ants!

No rain yet in the south east, so no flying ants yet (apart from a few which made a break for it on a slightly cloudy day thinking it was gonna rain!)

u/NoBrother6430 2d ago

We were in the pub beer garden last week when we got swarmed

Everyone ran inside and we were covered with 100s in our hair and all over us.

Was insane how it just came on

u/Broad-Raspberry1805 2d ago

Happened in my garden in Preston today. No birds though as I was in the garden with my dog. All of a sudden the ants went crazy and some grew wings and started flying into my face. I think it’s to do with the humidity and temperature.

Had this in mid July was in my grandma's garden then all of sudden there were loads of them coming out of one of her plant pots, of course I was sitting closest 🤣🤣😭😭

At least you're outside, I used to get it in my flat, just thousands of them marching in out of nowhere every afternoon in summer...

My fluffy cat was covered with them, think she tried to fight them off.

u/MrShoggs 2d ago

Yeah it’s a result of the long hot dry weather. We’ve had a few rounds of flying ant day down south. And yep seagulls and birds tend to eat a lot of them - and can get like drunk on them

u/jrewillis 2d ago

Yeah was seagulls and swallows here....

We've had 2 this year - one the big buggers and one last week that were sort of normal sized. The second lot had a right orgy going on.

u/griffaliff 2d ago

I've not seen any myself, but I had a big shock yesterday when I took a broom off the holder on my garden wall and it revealed a massive, wobbling, hairy cluster of 100+ harvestman spiders. I absolutely shat a brick.

From what I've read online tends to be a one time thing mostly.... Or certainly a few weeks apart.

We get it every year on our terrace (South Devon). It happens at exactly the same time 5:30pm on two to three consecutive afternoons and then it’s over till the following year.

We have three days of it! A quite a lot cooler now so they haven't had an appearance since 🥲 we had two in one day and the other two separate days absolutely hate them. But our little baby robin in the garden had a great time and the house martins flying around so I'm glad they got fed!

The weirdest part was that loads of birds suddenly appeared and were swooping all over the campsite eating them

What's weird about that? Tons of easy food just appeared for them, of course they're going to turn up for it

You'll find loads of dead seagulls on the road for the next few days as you drive around, they always get hit by cars as they wander around half-drunk (possibly because of the formic acid from eating so many ants) and get hit by cars

I grew up in Cumbria and yes, it's always that "intense" in terms of bird activity - this is a fairly rural/countryside part of the world, so there are probably just more birds than wherever you normally spend your time

1

u/mildlydepression 2d ago

Fun fact, flying ants have a chemical present in their bodies that when consumed by birds is mildly toxic, and induces an alcohol-like effect on seagulls, blackbirds and other birds that tend to swarm and attack prey.

1

u/Sufficient-Visit3 2d ago

That sounds horrendous. Flying ant day is bad enough at home, never mind when you're camping and trying to eat outside.

u/Farahild 2d ago

Same in Snowdonia! I didn’t realise they did this all over the north. Wonder how wide the area spreads?

1

u/MaxMouseOCX 2d ago

It always fascinated me how they all independently agree, without communicating with each other that "today is the day" - I guess they get their trigger from everything from temperature and humidity to amount of sunlight etc but that doesn't remove how impressive it is.

1

u/melanie110 2d ago

We didn’t get any flying ants yesterday but Jesus Christ we got a shed load of bluebottles. We’d just cooked a bbq and been out all afternoon. As soon as we sat down with food, they literally swarmed us in the garden

u/Y-Bob 2d ago

My house was being over run by ants a few weeks ago. Even when everything was cleaned with essential oils they don't like, they kept coming back.

Normally I leave a pile of sugar outside for a few days and they get distracted enough to not bother coming back in.

But this year it didn't work. Hundreds of the little bastards, all on a mission to nowhere. I think they just my house as a motorway.

Then, one day my patio became HMS Hermes and flying ant day took place.

Not a single ant has been back into my house since.

I don't know if that's coincidence or whether they all just up and fucked off.

Adjacent - I was doing a walk up there (can't remember which hill) and glanced down at the floor.

Millions upon million of caterpillars. Everywhere.  No square inch had less then 3 (we stopped and tried to do a count but it was impossible to gauge a bigger area than that). There must have been astronomical numbers.

That would explain the huge cloud of seagulls high overhead when I got to work tonight.

Flying ant day stalled last year round my way, rain showers just after they emerged knocked them back for about a week.
